Question

Consider the two structures $F_{2}C{l}^{-}$ and $F_{2}C{l}^{+}$
Select the correct statement.

• A. $F_{2}C{l}^{-}$ is bent and $F_{2}C{l}^{+}$ is linear
• B. $F_{2}C{l}^{-}$ is linear and $F_{2}C{l}^{+}$ is bent
• C. Both are bent
• D. Both are linear

Answer 1

The correct option is B $F_{2}C{l}^{-}$ is linear and $F_{2}C{l}^{+}$ is bent

$F_{2}C{l}^{-}$ has three lone pairs and two bond pairs, its representation will be $A{B}_2{L}_3$ and according to VSEPR theory the shape will be linear.
$F_{2}C{l}^{+}$ has two lone pairs and two bond pairs, its representation will be $A{B}_2{L}_2$ so according to VSEPR theory it will be bent.
