Some Basic Principles Of Organic Chemistry Question 14
Question: Examine the following common chemical structures to which simple functional groups are often attached (i) (ii) (iii) (iv) $ CH_3CH_2CH_2CH_2- $ (v) $ H_2C=C<\begin{matrix} H \\ H \\ \end{matrix} $ Which of these systems have essentially planar geometry [CBSE PMT 1995]
Options:
A) (i) and (v)
B) (ii) and (iii)
C) (ii), (iii) and (iv)
D) (iv)
Show Answer
Answer:
Correct Answer: A
Solution:
(i) Benzene and its derivatives are always planar because all the carbon in benzene are $ sp^{2} $ hybridized.
(v) $ CH_2=C<\begin{matrix} H \\ H \\ \end{matrix} $ Both the carbon are $ sp^{2} $ hybridized.
Therefore planar.
