Answer
(b) 1-Bromo-2-methylbutane
Explanation: First, we need to identify the longest carbon chain. Once we do that, the actual structure should read $CH _3- CH _2$ $- CH \left( CH _3\right)- CH _2- Br$. - Br , the functional halide group is attached to the first carbon atom (1- Bromo), so we start the numbering from that position. The methyl group branch is bond to the second carbon atom in the chain(2-methyl). The number of carbons in the unbranched parent chain is four, thus giving the name butane. The IUPAC is named 1-Bromo-2methylbutane.
