Answer the following question:
Arrange the following in the order of property indicated against each set:
a. $H F, H C l, H B r, H I$ - increasing bond dissociation enthalpy
b. $H_{2} O, H_{2} S, H_{2} S e, H_{2} T e$ - increasing acidic character.

Solution

(i) $H I < H B r < H C l < H F$ - increasing bond dissociation enthalpy
(ii) Hydracids of VI group elements act as weak acids. The strength increases in the order $H_{2} O < H_{2} S < H_{2} S e < H_{2} T e$ .
