Tertiary Carbon in Organic Compounds

Tertiary carbon is a carbon atom that is bonded to three other carbon atoms in an organic compound. It is denoted as 3° carbon. The presence of tertiary carbon in organic compounds affects their physical and chemical properties. Here are the given organic compounds and their tertiary carbon presence.

1. Iso-Octane

Iso-Octane, also known as 2,2,4-trimethylpentane, is an organic compound that is commonly used as a fuel additive in gasoline. It has eight carbon atoms, each of which is a secondary carbon atom. Therefore, there is no tertiary carbon atom present in iso-octane.

2. 3-Methylpentane

3-Methylpentane is an organic compound that is derived from pentane. It has five carbon atoms, one of which is a tertiary carbon atom. The tertiary carbon atom is located at the third position from the methyl group.

3. Isopentane

Isopentane is an organic compound that is also derived from pentane. It has five carbon atoms, none of which is a tertiary carbon atom. All the carbon atoms in isopentane are secondary carbon atoms.

4. Isopropyl Amine

Isopropyl amine is an organic compound that is an amine derivative of propane. It has three carbon atoms, one of which is a primary carbon atom, and the other two are secondary carbon atoms. There is no tertiary carbon atom present in isopropyl amine.

In conclusion, among the given organic compounds, only 3-methylpentane has a tertiary carbon atom present.
