What would be the formula of the next alkane if one hydrogen from butane is replaced by a methyl group?

Explanation

To solve the problem of determining the formula of the next alkane when one hydrogen from butane is replaced by a methyl group, we can follow these steps:

### Step 1: Identify the formula for butane
Butane is an alkane with 4 carbon atoms. The general formula for alkanes is given by:
\[ C_nH_{2n+2} \]
For butane, where \( n = 4 \):
\[ C_4H_{2(4)+2} = C_4H_{10} \]
