Problem: What is the Lewis electron-dot structure for a molecule of hydrogen chloride?

FREE Expert Solution

We are being asked to draw the Lewis structure of hydrogen chloride.

In drawing the Lewis structure:

STEP 1: Determine the total number of valence electrons

STEP 2: Determine the central atom based on the least electronegative atom

STEP 3: Represent bonding pairs using a line.

STEP 4: Distribute the electrons on the terminal atoms. Excess electrons are placed on the central atom.


First, Let’s write the formula for hydrogen chloride

• H is a non-metal from group 1A → H

• Chlorine is a non-metal from group 7A → Cl
