Chemistry Question on Organic Chemistry- Some Basic Principles and Techniques

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

A

120∘^{\circ} and 109∘^{\circ}28'

B

90∘^{\circ} and 109.5∘^{\circ}

C

109.5∘^{\circ} and 90∘^{\circ}

D

109.5∘^{\circ} and 120∘^{\circ}

Answer

120∘^{\circ} and 109∘^{\circ}28'

Explanation

Solution

It is an alkene, (i.e. contains double bond between
carbon atoms) so the bond angle is 120∘^{\circ} while
tetrachloro methane is an alkane, i.e. contains only
single bonds, so the bond angle is 109∘^{\circ}28'.
