LIST-I contains reactions and LIST-II contains major products

	LIST-I		LIST -II
A)		P)
B)		Q)
C)		R)
D)		S)
		T)

Match each reaction in LIST-I with one or more products in LIST-II and choose the correct option

1. - $\mathrm{A} \rightarrow \mathrm{P}, \mathrm{T}$ - $B \rightarrow Q$ - $\mathrm{C} \rightarrow \mathrm{R}$ - $D \rightarrow S$
2. - $A \rightarrow P, S$ - $B \rightarrow \mathbf{Q}$ - $\mathrm{C} \rightarrow \mathrm{S}$ - $D \rightarrow R$
3. - $\mathrm{A} \rightarrow \mathrm{S}, \mathrm{T}$ - $B \rightarrow S$ - $\mathrm{C} \rightarrow \mathrm{S}$ - $D \rightarrow R, S$
4. - $\mathrm{A} \rightarrow \mathrm{P}, \mathrm{S}$ - $B \rightarrow P, Q$ - $C \rightarrow R, S$ - $\mathrm{D} \rightarrow \mathrm{S}$

Solution

$\left(A\right)$ Bulky base is present, it will abstract proton, hence will undergo E2 reaction

$\left(B\right)$ Hydrogen ion will protonate the oxygen of methoxy group and make it a good leaving group, hence methanol and t-butyl bromide is formed.

$\left(C\right)$ Methoxy group will abstract proton. E2 elimination occur

$\left(D\right)$ It will undergo ${\mathrm{S}}_{\mathrm{N}}2$ mechanism.
