Vedclass · Answer

(A) Step $1$: Oxidation of cyclohexanol with $K_2Cr_2O_7$ gives cyclohexanone.Step $2$: Reaction of cyclohexanone with phenylmagnesium bromide $(C_6H_5MgBr)$ followed by hydrolysis gives $1-$phenylcyclohexanol.Step $3$: Acid-catalyzed dehydration of $1-$phenylcyclohexanol with $H^+$,heat gives $1-$phenylcyclohexene as the major product '$X$'.Step $4$: In $1-$phenylcyclohexene,the phenyl ring has $6$ $sp^{2}$ carbons and the double bond in the cyclohexene ring involves $2$ $sp^{2}$ carbons.Total $sp^{2}$ hybridised carbon atoms = $6 + 2 = 8$.

In the given reaction,the number of $sp^{2}$ hybridised carbon atoms in compound '$X$' is $.....$
