Question

# State True or False.Out of the following acid base-reactions, reaction (b) and(c) are possible.a. $$PH_3+\overset{\oplus}{N}H_4 \longrightarrow \overset{\oplus}{P}H_4+NH_3$$b. $$NH_3+P\overset{\oplus}{H}_4 \longrightarrow N\overset{\oplus}{H}_4+PH_3$$c. $$(CH_3)_3P+\overset{\oplus}{N}H_4 \longrightarrow (CH_3)_3\overset{\oplus}{P}H+NH_3$$d. $$(CH_3)_3N+PH_4^{\oplus} \longrightarrow (CH_3)_3\overset{\oplus}{N}H+PH_3$$

A
True
B
False

Solution

## The correct option is A Truea. $$PH_3+\overset{\oplus}{N}H_4 \longrightarrow \overset{\oplus}{P}H_4+NH_3$$b. $$NH_3+P\overset{\oplus}{H}_4 \longrightarrow N\overset{\oplus}{H}_4+PH_3$$c. $$(CH_3)_3P+\overset{\oplus}{N}H_4 \longrightarrow (CH_3)_3\overset{\oplus}{P}H+NH_3$$d. $$(CH_3)_3N+PH_4^{\oplus} \longrightarrow (CH_3)_3\overset{\oplus}{N}H+PH_3$$Out of the above acid base-reactions, reaction (b) and (c) are possible due to following reasons.Ammonia is more basic than phosphineAmmonia is less basic than $$\displaystyle (CH_3)_3P$$Chemistry
