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) CH3CH2CH2CH2 (v) H2C=C<HH 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 sp2 hybridized.

(v) CH2=C<HH Both the carbon are sp2 hybridized.

Therefore planar.
