Question

On moving from left to right in a period what is the order of acidic character of hydrides?

A. $$N{H_3} < {H_2}O < HF$$  
B. $$HF < {H_2}O < N{H_3}$$
C. $${H_2}O < HF < N{H_3}$$
D. $${H_2}O < N{H_3} < HF$$
Answer :   $$N{H_3} < {H_2}O < HF$$
Solution :
On moving from left to right in a period. the acidic character of hydrides increases. $$N{H_3}$$  is basic, $${H_2}O$$  is neutral and $$HF$$  is acidic.
