Answer 1

A) Identical.

Since both the functional groups ( -NH₂ and -CH₂OH) are above the plane in both structures and position of double bond is same.

The OH is attached to achiral center, so its position does not matter.

B) Diastereomers but not epimers

Cis-trans isomers have different configuration and are not mirror images to each other.

Epimers differ in their configuration at chiral centre. Since there is no chiral center in cis-trans or E/Z isomer, this is not an epimer.

C) Enantiomer

Stack the two molecules on each other and place a mirror in between them. All the -OH groups will be reflected. So, the given compounds are mirror images of each other and does not super-impose on each other.

D) Enantiomer

Keep the molecules as it is (sideways) and place a mirror in between the two molecules. The molecules are mirror images and does not super-impose on each other.

E) Constitutional isomers

Constitutional isomers have different atom to atom connectivity. This includes positional, structural and functional isomers.

The given compounds differ in functional groups. First has aldehyde group while second has ketone group.
