…….ring is the most strained. (Cyclopropane, Cyclobutane, Cyclopentane)

Stress & Strain

Define stress and strain?

Compare the orbital overlap in cyclopropane and alkane.

. Which of the following is more easily enolised? a. Cyclobutenone b. Triketo cyclobutane

The angle strain in cyclohexane is :

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 mol^(-1) , what is the ring strain in kJ mol^(-1) of cyclobutane ?
