3.49 (c) Oxygen's electrons

Postby Grace Lee 3G » Mon Oct 30, 2017 3:06 pm

How come the solutions manual shows oxygen as having 5 electrons when the periodic table's oxygen has 6 electrons?

The important thing you have to remember about drawing lewis structures is to satisfy the octet rule for each atom. There's no way to draw the lewis structure so that the oxygen has 5 electrons around it without preventing carbon a full octet.

When drawing Lewis structures, you count up total valence electrons for each atoms and draw bonds and lone pairs accordingly. If you follow the procedure established in lecture, you should get the diagram correctly.

The total valence electrons in the lewis structure are determined by adding up all the valence electrons. You have to satisfy the octet rule. You can do this by drawing bonds and lone pairs to get an accurate lewis structure.
