Question

Which of the following is true for cyclopropane?

• A. It is unstable due to torsional strain
• B. It is unstable due to angle strain
• C. It bears 9 bonds with electron density along internuclear axis
• D. It bears H-C-H bond angle of ${109}^{\circ }$ 28'

Answer 1

Answer: (A), (B), (D)

The correct options are
A It is unstable due to torsional strain
B It is unstable due to angle strain
D It bears H-C-H bond angle of ${109}^{\circ }$ 28'

In cyclopropane there is eclipsed conformation, hence it bears torsional strain. Due to angle strain, carbon-carbon bonds are not along inter-nuclear axis.
