Vedclass · Answer

(A) To determine the bond angle,we look at the hybridization and the number of lone pairs on the central atom:$1$. $CO_2$: $sp$ hybridization,linear geometry,bond angle = $180^{\circ}$.$2$. $CH_4$: $sp^3$ hybridization,tetrahedral geometry,bond angle = $109.5^{\circ}$.$3$. $NH_3$: $sp^3$ hybridization,trigonal pyramidal geometry,one lone pair,bond angle = $107^{\circ}$.$4$. $H_2O$: $sp^3$ hybridization,bent geometry,two lone pairs,bond angle = $104.5^{\circ}$.Due to the presence of two lone pairs on the oxygen atom in $H_2O$,the lone pair-lone pair repulsion is greater than the lone pair-bond pair repulsion,which compresses the $H-O-H$ bond angle to $104.5^{\circ}$,the smallest among the given options.

List-$I$ Molecule/ion	List-$II$ Bond pair : lone pair (on the central atom)
$A. ICl_2^-$	$I. 4 : 2$
$B. H_2O$	$II. 4 : 1$
$C. SO_2$	$III. 2 : 3$
$D. XeF_4$	$IV. 2 : 2$

List-$I$	List-$II$
$A. XeF_4$	$I. See-saw$
$B. SF_4$	$II. Square planar$
$C. NH_4^{+}$	$III. Bent T-shaped$
$D. BrF_3$	$IV. Tetrahedral$
