Which of the following statements is not true?

Options

A. The different arrangement formed by rotations about a single bond are called conformations.
B. The repulsion felt by the bonding electrons of one substituent as they pass close to the bonding electrons of another substituent is called steric strain.
C. The strain arises due to repulsion between electron clouds of the interacting atom or groups is called steric strain.
D. The investigation of the various conformation of the compound and their relative stabilities is called conformation analysis.

Answer

B

Explanation

The repulsion felt by the bonding electrons of one substituent as they pass close to the bonding electrons of another substituent is called torsional strain.
