The angle strain in cyclobutane is:

Options

A. `19^(@) 22`'
B. `9^@ 44`
C. `24^@ 44`
D. `29^@ 16.`

Answer

B

Explanation

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.`
