Q. Which of the following has maximum angle strain?

4638 202 NTA AbhyasNTA Abhyas 2020Organic Chemistry – Some Basic Principles and Techniques Report Error

A

Propane

16%

B

Cyclopropane

68%

C

n-butane

10%

D

Cyclobutane

5%

Solution:

Here cyclopropane has maximum angle strain followed by cyclobutane.

Angle strain is directly proportional to angle of deviation 'd'.

$Angle strain \propto d \propto \frac{1}{inner bond angle}$ .
