The major product obtained in the reaction is:

If the starting material is $1-$methyl$-1,2-$epoxycyclopentane,determine which compound correctly represents the product of its reaction with sodium methoxide in methanol.

$A$ mixture of $1 \ g$ each of chlorobenzene,aniline,and benzoic acid is dissolved in $50 \ mL$ of ethyl acetate and placed in a separating funnel. $5 \ M \ NaOH$ $(30 \ mL)$ was added to the same funnel. The funnel was shaken vigorously and then kept aside. The ethyl acetate layer in the funnel contains:
