The isomers for the molecular formula C3H8O include methoxyethane, propan-1-ol and propan-2-ol. Each isomer is obtained by arranging the atoms in the C3H8O molecular formula into a different structural formula. The first isomer, methoxyethane, is an ether, and the other two isomers are alcohols.


Methoxyethane is also called methyl ethyl ether and appears as a colorless liquid. Its formula is written as follows: CH3-O-CH2-CH3.

Propan-1-ol has the formula CH3-CH2-CH2-OH and is also referred to as n-propanol, n-propyl alcohol or 1-hydroxypropane. Propan-1-ol is a colorless liquid used as a solvent.

Propan-2-ol, also called isopropanol and isopropyl alcohol, has the following formula: CH3-CH(OH)-CH3. This compound is used as a solvent and can be applied topically as an antiseptic and disinfectant.
