Question

The $Cl-C-Cl$ angles in $1,1,2,2$-tetrachloroethene and tetrachloromethane respectively will be about :

• A. ${120}^{\circ }$ and ${109.5}^{\circ }$
• B. ${90}^{\circ }$ and ${109.5}^{\circ }$
• C. ${109.5}^{\circ }$ and ${90}^{\circ }$
• D. ${109.5}^{\circ }$ and ${120}^{\circ }$

Answer 1

The correct option is A ${120}^{\circ }$ and ${109.5}^{\circ }$

The $Cl-C-Cl$ angles in $1,1,2,2$-tetrachloroethene and tetrachloromethane, respectively, will be about :
${120}^{\circ }$ and ${109.5}^{\circ }$
In $1,1,2,2$-tetrachloroethene, the carbon atom is $s{p}^2$ hybridized which results in bond angle of ${120}^0$.
In tetrachloromethane the carbon atom is $s{p}^3$ hybridized which results in bond angle of ${109.5}^0$.
