Question

Angle strain in cyclopropane is :

• A. $24^o{44}^{\prime }$
• B. $9^o{44}^{\prime }$
• C. ${44}^{\prime }$
• D. $-5^o{16}^{\prime }$

Answer 1

The correct option is A $24^o{44}^{\prime }$

Angle strain in cyclopropane is $24^o{44}^{\prime }$
Deviation $d=\frac{{109}^o{28}^{\prime }-\alpha }{2}$
$\alpha$ is the bond angle in cyclopropane.
Deviation $d=\frac{{109}^o{28}^{\prime }-{60}^o}{2}=+{24}^o{44}^{\prime }$
