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

A

`NH_(3) lt H_(2)O lt HF`

B

`HF lt H_(2)O lt NH_(3)`

C

`H_(2)O lt HF lt NH_(3)`

D

`H_(2)O lt NH_(3) lt HF`

Text Solution

Verified by Experts

The correct Answer is:
A

On moving from left to right in a period, the acidic character of hydrides increases. `NH_(3)` is basic, `H_(2)O` is neutral and HF is acidic.

Explain the following : (i) Nonmetallic character increases in going from left to right in a period . (ii) The basic nature of oxides of the elements decreases in going from left to right in period.

Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : Metallic character decreases and non-metallic character increases on moving from left to right in a period. Reason (R) : It is due to increase in ionisation enthalpy and decrease in electron gain enthalpy, when one moves from left to right in a period. In the light of the above statements, choose the most appropriate answer from the options given below :
