Chemistry Question on Bond Parameters

Percentage covalent character is maximum in :

A

\ceBeX2\ce{BeX_{2} }

B

\ceMgX2\ce{ MgX_2}

C

\ceCaX2\ce{CaX_2 }

D

\ceSrX2\ce{SrX_2 }

Answer

\ceBeX2\ce{BeX_{2} }

Explanation

Solution

Among Be2+,Mg2+,Ca2+,Sr2+;Be2+ {Be^{2+} , Mg^{2+}, Ca^{2+}, Sr^{2+} ; Be^{2+}} has highest polarizing power ; So BeX2 {BeX_2} has maximum covalent character.
