Answer 1

Concepts and reason

This problem is based on the chiral character of organic molecules.

Chiral molecule is a molecule which possesses an asymmetric carbon (chiral carbon). An asymmetric carbon is the carbon which is connected to the four completely different substituents. Moreover, a chiral molecule does not contain the plane of symmetry.

Fundamentals

An asymmetric carbon is the carbon attached to the four completely different groups of atoms. A plane of symmetry is an imaginary plane which bisects the compound into two equal halves. It can be vertical as well as horizontal.

Answer 2

An atom which is attached to 4 different groups, then it is said to be chiral. The chiral centers are indicated with blue color. The carbon atom is attached to 4 different groups. So, the molecule is chiral Br b) The two carbons are attached to the four different groups. So, the given molecule has two chiral centers. c) None of the carbon atoms in the given molecule are attached to four different groups. Thus, the molecule has no chiral centers HO H2 H Br CCH3 The carbon is attached to the four different groups. So, the given molecule has one chiral centers. H3C H F

e) Br Plane of symmetry CH3 Bri ..H3 The molecule has a plane of symmetry. So, the molecule has no chiral centers
