Give the formula and name of the alkane which contains four carbon atoms in each molecule.

(N/A) The general formula for an alkane is $C_{n}H_{2n+2}$,where $n$ is the number of carbon atoms.
Given that the molecule contains $n = 4$ carbon atoms.
Substituting $n = 4$ into the formula: $C_{4}H_{2(4)+2} = C_{4}H_{8+2} = C_{4}H_{10}$.
The alkane with four carbon atoms is named Butane.
