Vedclass · Answer

(B) The reaction of $3$-chloro-$2$-methylpent-$4$-ene with aqueous $NaOH$ is a nucleophilic substitution reaction ($S_N1$ or $S_N2$ depending on conditions,but here it leads to the substitution of $-Cl$ by $-OH$).The product '$P$' is $3$-methylpent-$4$-en-$2$-ol.The structure of the product contains one double bond $(C=C)$.Since each double bond consists of one $\pi$ bond,and each $\pi$ bond contains $2$ electrons,the total number of $\pi$ electrons in the product is $2$.

Consider the reaction shown below. The number of $\pi$ electrons present in the major product '$P$' is ...... .
