Question

22. The bond angle betiveen carbon atoms in cyclohexane is....
(a) 109°28 (b) 60° (c) 90°
(d) 120°
​

Answer 1

Answer:109°28

Explanation:

Answer 2

The correct option is d.

• The chemical formula of cyclohexane is $C_6H_{12}$.
• The bond angle between carbon atoms in cyclohexane is 120°.
• Thus it suffers from angle strain and to get relief from this angle strain cyclohexane exists in chair and boat conformations.
• In-chair confirmation of cyclohexane the bond angle between the carbon atoms is 109°28'.
• Thus in the chair conformation, it does not suffer from any angle strain.
