When applying VSEPR theory to determine the geometry about a central atom,it is important to count the total number of bonded and nonbonded electron groups.Separately consider the two atoms highlighted with an arrow in the molecule shown below.How many bonded electron groups must be considered for each of these central atoms?

Question

Quizplus · Accepted Answer

For the carbon atom highlighted with the arrow, there are three bonded electron groups (one with the hydrogen atom and two with the adjacent carbon atoms). 
For the oxygen atom highlighted with the arrow, there are two bonded electron groups (both with the adjacent carbon atoms).
