Question

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

• A. ${109.5}^o$ and ${90}^o$
• B. ${120.0}^o$ and ${109.5}^o$
• C. ${90}^o$ and ${109.5}^o$
• D. ${109.5}^o$ and ${120}^o$

Answer 1

Answer: (B)

${120.0}^o$ and ${109.5}^o$

The $Cl-C-Cl$ angle in $1,1,2,2$ - tetrachloroethene and tetra chloromethane respectively will be about ${120.0}^o$ and ${109.5}^o$.

$C{l}_{2}C=C{Cl}_2$ has ${sp}^2$ - hybridization in both the central C atom. $C{Cl}_4$ has ${sp}^3$ - hybridization.

Option B is correct.
