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

$(a)\;120^{\circ}\;and\;109.5^{\circ} \\ (b)\;90^{\circ}\;and\;109.5^{\circ} \\ (c)\;109.5^{\circ}\;and\;90^{\circ} \\ (d)\;109.5^{\circ}\;and\;120^{\circ}$

Since tetrachloroethene is an alkene (substitute) it has $SP^2$ hybridized $C$- atoms so $Cl - C - Cl$ bond angle is $120^{\circ}$
Tetrachlorometer is an alkane (substituted ) and in it the bond angle is $109^{\circ} 28' \;(SP^3)$ hybridisation
Hence a is the correct answer.
