Question

In the following reaction, compound $Q$ is obtained from compound $P$ via an ionic intermediate.\ What is the degree of unsaturation of Q?

Professor PC Thomas Classes · Answer

(18) :\ Degree of unsaturation =\ $\frac{(2 	imes 	ext { no. of Carbon atoms })+2-	ext { no. of Hydrogen atoms }}{2}$ $$ =\frac{(2 	imes 25)+2-16}{2}=\frac{36}{2}=18 $$ (Oxygen has no effect on degree of unsaturation)\ Thus, degree of unsaturation in $Q=18$.\
