$HBr$ (Strong acid)

Vedclass · Answer

(C) The acidic strength of hydrides of non-metals increases down the group as the bond dissociation energy decreases. $HF$ is a weak acid due to strong hydrogen bonding. $HBr$ is a strong acid because the $H-Br$ bond is relatively weak compared to $H-F$. $H_2Te$ is a stronger acid than $H_2Se$ due to the increase in atomic size down the group. $H_3P$ (Phosphine) is a very weak base. Therefore,the statement '$HBr$ (Strong acid)' is correct.

Which of the following statements is correct for the compounds $HF, HBr, H_2Se, H_2Te, H_3P$?
