Vedclass · Answer

(D) To be isoelectronic,the total number of valence electrons must be the same.For $IBr_{2}^{-}$: $7 (I) + 2 	imes 7 (Br) + 1 (	ext{charge}) = 22$ valence electrons.For $XeF_{2}$: $8 (Xe) + 2 	imes 7 (F) = 22$ valence electrons.Both species have $22$ valence electrons,so they are isoelectronic.Both $IBr_{2}^{-}$ and $XeF_{2}$ have $3$ lone pairs and $2$ bond pairs around the central atom,resulting in a linear geometry ($sp^3d$ hybridization),making them isostructural.

List-$I$ (molecules/ions)	List-$II$ (No. of lone pairs of $e^-$ on central atom)
$A$. $IF_7$	$I$. Three
$B$. $ICl_4^-$	$II$. One
$C$. $XeF_6$	$III$. Two
$D$. $XeF_2$	$IV$. Zero

$A$	$B$
$CH_3OH$	$CH_3OCH_3$
