Question

Change the following condensed structure to Kekulẻ structures:

a. CH₃NH(CH₂)₂CH₃

b.(CH₃)₂CHCl

c.(CH₃)_3CBr

d.(CH₃)₃C(CH₂)₃CHO

Short answer

Organic structures are represented as structural formulas with bonds indicated by short lines. Such structural representations are known as the Kekule structures. Unlike the Lewis structure, lone pairs are omitted in the Kekule structure.

Step-by-step solution

Definition of Kekule structure

Organic structures are represented as structural formulas with bonds indicated by short lines. Such structural representations are known as the Kekule structures. Unlike the Lewis structure, lone pairs are omitted in the Kekule structure.

Subpart (a) Drawing the Kekule structure of CH3NH(CH2)2CH3 .

From the condensed formulas, omit the lone pair of electrons that represent each bond with short straight lines, and form the respective Kekule structure.

Subpart (b) Drawing the Kekule structure of .(CH3)2CHCl

The Kekule structure of the given compound is shown below.

Subpart (c) Drawing the Kekule structure of .CH3)3CBr

The Kekule structure of the given compound is shown below.

Subpart (d) Drawing the Kekule structure of .(CH3)3C(CH2)3CHO

The Kekule structure of the given compound is shown below.
