Chemistry - CHEMICAL BONDING Question with Solution | TestHub

The correct statement is D.

A. The acidic strength order is $H_{2}S>H_{2}O$ because sulfur is larger than oxygen, leading to a weaker H-S bond.

B. A p$\pi$-p$\pi$ bonding M.O. has g (gerade) symmetry if it is formed by side-on overlap of p-orbitals (e.g., $\pi$ bonding MO).

C. $NC{l}_3$ on hydrolysis gives $N{H}_3$ and HOCl. $N{F}_3$ is stable and does not hydrolyze under ordinary conditions.

D. The bond angle order is $O{F}_2<H_{2}O<C{l}_{2}O<Cl{O}_2$. This order is due to electronegativity differences and lone pair repulsions.
