$H_2O$

Vedclass · Answer

(C) The bond angles for the given molecules are as follows:$BeF_2$: $180^o$ ($sp$ hybridization,linear geometry).$CH_4$: $109^o 28'$ ($sp^3$ hybridization,tetrahedral geometry).$NH_3$: $107^o$ ($sp^3$ hybridization,one lone pair,pyramidal geometry).$H_2O$: $104.5^o$ ($sp^3$ hybridization,two lone pairs,bent geometry).Due to the presence of two lone pairs on the oxygen atom in $H_2O$,the $lp-lp$ repulsion is greater than the $lp-bp$ repulsion in $NH_3$,resulting in the smallest bond angle among the given options. Thus,the correct option is $(C)$.
