Question

Which of the following statement is not true ?

• A. The different arrangements 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 atoms or groups is called steric strain
• D. The study of the various conformations of the compound and their relative stabilities is called conformational analysis.

Answer 1

Answer: (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

Answer 2

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