The angle strain in cyclopentane is

The angle strain in cyclohexane is :

A : Cyclohexane is more stable than cyclopentane. R : According to Baeyer strain theory angle strain in cyclohexane is more than cyclopentane.

Assertion: Cyclobutane is less stable than cyclopentane Reason : The bond angles in cyclobutane and cyclopentane are 90^@ and 108^@ , respectively

There is no ring strain in cyclohexane, but cyclobutane has an angle strain of 9^(@) 44'. If Delta H_(c)^(@) of cyclohexane per (CH_(2)) group is 660 kJ mol^(-1) and Delta H_(c)^(@) of cyclobutane is 2744 kJ mmol^(-1) , what is thering strain in kJ mol^(-1) of cyclobutane ?
