Question

Question: Draw four additional resonance structures for the following cation. Then draw the resonance hybrid.

Short answer

Answer

Step-by-step solution

Step-by-Step SolutionStep 1: Making of resonance structures

The electrons that are present only in multiple bonds and in lone pairs can move. The number of lone pairs should remain constant during the movement of electrons.

A better resonance structure has a minimum charge, and the delocalized electrons are distributed over a greater atom.

 Step 2: Resonance hybrid structure

A resonance hybrid structure has a bond delocalized over all those atoms which have a double bond in any one of the resonance structures

The resonance structures and the resonance hybrid structure of the given compound

The five resonance structures are obtained by electron movement and its representation.

Five resonance structures of the given compound

Since all the resonance structures have the same charge and the same number of bonds, and each structure has one carbon atom with an incomplete octet, all the resonance structures contribute equally to the resonance hybrid structure.

The resonance hybrid structure has the characteristics of all the resonance structures and is given as follows:
