Problem: Which one of the following is expected to exhibit resonance?(A) CO2 (B) NH4+ (C) HCN (D) NO2−

FREE Expert Solution

We are being asked to identify which one of the given molecules will exhibit resonance

A resonance structure shows the delocalization of electrons in a molecule.

Resonance structures differ only in the placement of electrons.

To determine this, we will have to draw the Lewis Structures of all molecules.

Lewis structure can be drawn using this method.

Step 1: Determine the central atom.

Step 2: Calculate the total number of valence electrons present.          

Step 3: Draw the Lewis Structure for the molecule.
