Reactivity towards $H^{+}$ is $NH_3 > AsH_3$.

Vedclass · Answer

(D) In $AsH_3$,the central atom $As$ has a large size and low electronegativity.According to Drago's rule,for elements of the third period and below with low electronegativity,the bond angles are close to $90^{\circ}$,and hybridization does not occur.Therefore,the $As-H$ bonds are formed using pure $p$-orbitals,and the lone pair resides in a pure $s$-orbital.Since the lone pair is in an $s$-orbital,it is not available for donation,making $AsH_3$ a very weak base compared to $NH_3$.Thus,the reactivity towards $H^{+}$ follows the order $NH_3 > AsH_3$,and the lone pair is in a pure $s$-orbital (not $p$-orbital).Statement $D$ is correct.

Which of the following statements is correct regarding $AsH_3$?
