The carbon atom uses the 2s and the 2p orbitals for bonding. Since carbon is a tetravalent atom, one would expect there to be two kinds of carbon-hydrogen bonds. However, the fact is, all four carbon-hydrogen bonds are identical. Why is this possible?

a) the one s and three p orbitals can combine to form four equivalent atomic orbitals

b) the one s and three p orbitals can hybridize forming a tetrahedral orientation
c) the one s and three p orbitals can form sp3 hybrid orbitals

d) a and b only

e) All of the above

The chiral center is the point or carbon atom which possesses all the four different groups attached to it. A chiral center is commonly denoted by an asterisk.
 For More Chemistry Notes and Helpful Content Subscribe Our YouTube Chanel - Chemistry Explain  

Free Chegg Answer

The chiral center is the point or carbon atom which possesses all the four different groups attached to it. A chiral center is commonly denoted by an asterisk (*).
(a)
The structure of the given molecule is as follows:

Now we can find the carbon atom is chiral or not as described as follows:
Carbon number 1 has two bromine atoms attached to it. Thus, C-1 carbon is not a chiral center.
Carbon number 2 also has two chlorine atoms attached to it. Thus, C-2 carbon is also not a chiral center.
Hence, the given structure does not show any chiral center(s).

(b)
The structure of the given molecule is as follows:

Carbon number 1 consists of all the four different groups. It has a hydrogen atom above it, a chlorine atom at its left, a bromine atom below it, and two carbon atoms with different substituents at its right side. Thus, C-1 carbon is a chiral carbon or chiral center.
Carbon number 2 does not consist of all the four different groups attached to it. It consists of hydrogen atom above it and the hydroxyl group below it. But at its right and left side, it has the same group (carbon with one hydrogen atom, one chlorine atom, and one bromine atom). Thus, C-2 carbon is not a chiral carbon or chiral center.
Carbon number 3 consists of all the four different groups. It has a hydrogen atom above it, a chlorine atom at its right, a bromine atom below it, and two carbon atoms with different substituents at its left side. Thus, C-1 carbon is a chiral carbon or chiral center.
Hence, the given structure shows two chiral centers.

(c)
The structure of the given molecule is as follows:

Now we can find the carbon is chiral or not as described as follows:

Carbon number 1 has three same groups (hydrogen atoms) attached to it. Thus, C-1 carbon is not a chiral center.
Carbon number 2 consists of all the four different groups attached to it. It consists of a hydrogen atom above it and the hydroxyl group below it. On its left and right side, both the groups are different because the right side consists of the aldehyde group while the left side does not consist of this group.
On its right side also consists of two carbon atoms with a hydroxyl group and a hydrogen atom while the left side consists of only one carbon atom with all the hydrogen atoms. Thus, all the four groups are different and hence, C-2 carbon is a chiral carbon or chiral center.
Carbon number 3 consists of all the four different groups attached to it. It consists of a hydrogen atom above it and the hydroxyl group below it. On its left and right side, both the groups are different because the right side consists of the aldehyde group while the left side does not consist of this group.
Carbon number 4 consists of all the four different groups attached to it. It consists of a hydrogen atom above it and the hydroxyl group below it. On its left and right side, both the groups are different because the right side consists of the aldehyde group while the left side does not consist of this group. Its left side consists of three carbon atoms with a hydroxyl group and hydrogen atom while the right does not consist of such groups. Thus, all the four groups are different and hence, C-4 carbon is a chiral carbon or chiral center.
Carbon number 5 consists of a double bond with oxygen. Any carbon with a double bond consists of less than four groups attached to it. The definition says that the chiral center must consist of four different groups attached to it. This carbon consists of three groups attached to it, thus, the C-5 carbon is not a chiral carbon or chiral center.
Hence, the given structure shows two chiral centers.

(d)
The structure of the given molecule is as follows:

Now we can find the carbon is chiral or not as described as follows:

Carbon number 1 has two same groups (hydrogen atoms) attached to it. Thus, C-1 carbon is not a chiral center.
Carbon number 2 consists of all the four different groups attached to it. It consists of a hydrogen atom above it and the hydroxyl group below it. On its left side, it consists of one carbon atom while on its right side it consists of four carbon atoms. Thus, C-2 carbon is a chiral center.
Carbon number 3 consists of all the four different groups attached to it. It consists of a hydrogen atom above it and the hydroxyl group below it. On its left side, it consists of two carbon atoms while on its right side it consists of three carbon atoms. Thus, C-3 carbon is a chiral center.
Carbon number 4 consists of all the four different groups attached to it. It consists of a hydrogen atom above it and the hydroxyl group below it. On its left side, it consists of three carbon atoms while on its right side it consists of two carbon atoms. Thus, C-4 carbon is a chiral center.
Carbon number 5 has two same groups (hydrogen atoms) attached to it. From the definition, it gets clear that chiral carbon is the one which have all the four different groups attached to it. No two groups can be similar. Thus, C-5 carbon is not a chiral center.
Hence, the given structure shows three chiral centers.

Carbohydrates possesses handedness exists in two forms left-handed form and a right-handed form. Mirror image is the reflection of an object in the mirror. There are two classes of mirror images: superimposable mirror images are images that coincide at all points, nonsuperimposable mirror images are images where not all points coincide. A chiral center is an atom in a molecule that has four different functional groups bounded to it in a tetrahedral orientation.

(a)
The molecule does not possess a chiral center. No carbon in the molecule will bound to four different functional groups.

(b)
The molecule possesses a chiral center. Carbon – 3 of the molecule will bind to four different groups (H, OH, CH₃, CH₂).

(c)
The molecule possesses a chiral center. Carbon – 3 of the molecule will bind to four different groups (H, OH, CH₃, CH).

(d)
The molecule does not possess a chiral center. No carbon in the molecule will bound to four different functional groups.

Biochemistry is the study of chemical substances found in the living organisms and the chemical interactions of these substances with each other. A biochemical substance is a chemical substance found within a living organism. The biochemical substance again divides into bioorganic and bioinorganic substance.

(a)
Bioorganic substances are slightly more abundant than bioinorganic substances – The given statement is.
Usually human body contains many bioorganic substances including carbohydrates, lipids, proteins and nucleic acids. Such substances make up only about one-fourth of total body mass. Bioinorganic substances make the remaining body mass.

(b)
Bioinorganic substances are much more abundant than bioorganic substances – The given statement is.
Bioinorganic substances include water and inorganic salts make two-thirds of the total body mass. So, bioinorganic substances are much more abundant than bioorganic substances.
