Problem: Write a Lewis structure for each of the following compounds, then answer the following questions about the Lewis structure.Compounds: SOCl2, ethanol (CH3CH2OH), and carbon dioxide.Questions:A. How many valence electrons does each compound have?B. How many bonded electrons does each compound have?C. How many lone pairs of electrons does each compound have?D. How many single bonds does each compound have?

FREE Expert Solution

We are asked to determine the number of valence electrons, bonded electrons, lone pairs of electrons, single bonds in each compound.


Recall that 

  • Valence electrons are the electrons in the outer shell
  • Bonded electrons are involved in a chemical bond. There are 2 electrons in a bond. 
  • Lone pair electrons are pair of valence electron not shared with another atom
  • Single bonds are sigma bonds formed by head-on overlapping of atomic orbitals


To determine these, we are going to draw the Lewis Structure of each compound.
