Organic Chemistry Some Basic Principles And Techniques Ques 23
23. The $Cl-C-Cl$ angle in $1,1,2,2$-tetrachloroethene and tetrachloromethane respectively will be about
[1988]
(a) $120^{\circ}$ and $120^{\circ}$
(b) $90^{\circ}$ and $109.5^{\circ}$
(c) $109.5^{\circ}$ and $90^{\circ}$
(d) $120^{\circ}$ and $109.5^{\circ}$
Show Answer
Answer:
Correct Answer: 23.(d)
Solution:
- (d) Tetrachloroethene being an alkene has $s p^{2}$ hybridized $C-$ atoms and hence the angle $Cl-C-Cl$ is $120^{\circ}$ while in tetrachloromethane, carbon is $s p^{3}$ hybridized, therefore the angle $Cl-$ $C-Cl$ is $109.5^{\circ}$.
