Concept explainers
Interpretation:
Octet rule must be used to draw Lewis structures of all the possible compound with the formula C3H8O.
Concept introduction:
Lewis dot structure is the representation of a molecule with the valence electrons shown as dots.
C3H8O is a general molecular formula which represents structures for alcohols and ether.

Explanation of Solution
Two alcohols are possible with the general formula C3H8O. One is Propan-1-ol and another is propan-2-ol. In all the structures octet rule is followed as per which there are eight electrons in all the participating atoms including bond pairs and lone pairs of electrons except hydrogen.
One ether is possible with this formula which is methoxyethane with the formula CH3OCH2CH3.
All the Lewis dot structures possible for C3H8O are given below.
