Give the IUPAC name of the alkane having the lowest molecular mass that contain a quaternary carbon.

Explanation

To find the IUPAC name of the alkane with the lowest molecular mass that contains a quaternary carbon, we can follow these steps:

### Step 1: Understand Quaternary Carbon
A quaternary carbon is a carbon atom that is bonded to four other carbon atoms and has no hydrogen atoms attached to it. This means that all four valencies of the carbon are satisfied by carbon substituents.

### Step 2: Identify the Smallest Alkane
We need to identify the smallest alkane that can have a quaternary carbon. The simplest alkane is methane (CH₄), but it does not have a quaternary carbon because it has only one carbon atom.
