The angle strain in cyclobutane is:...

The angle strain in cyclobutane is:

A

`19^@22'`

B

`9^@44'`

C

`24^@44'`

D

`29^@16'`

Text Solution

Verified by Experts

The correct Answer is:
a
According to Baeyer's strain theory, the amount of the strain is directly proportional to the angle through which a valency bond has deviated from its normal position . i.e., Amount of deviation (d)=1/2 (`109^@28'` -valency angle ) in cyclobutane (d)=1/2 `(109^@28'-90^@)=9^@44'`
