$CH_4$

Vedclass · Answer

(B) The bond angle depends on the hybridization of the central atom and the repulsion between lone pairs and bond pairs. In $CH_4$,the central atom $C$ is $sp^3$ hybridized with no lone pair,resulting in a tetrahedral geometry with a bond angle of $109.5^{\circ}$. In $NH_3$,$H_2O$,and $PH_3$,the central atoms have lone pairs which cause bond pair-lone pair repulsion,leading to a decrease in bond angle from the ideal tetrahedral angle. Specifically,$PH_3$ has a bond angle of approximately $93.5^{\circ}$ due to the lack of hybridization and the large size of the $P$ atom. Therefore,$CH_4$ has the greatest bond angle among the given options.

The bond angle $H-X-H$ is the greatest in the compound
