1-chlorobutane

Explanation:

The IUPAC nomenclature of alkyl halides are given as follows:

1. Select the longest possible carbon chain which has the halogen attached to it and name the parent chain from where the halogen gets the highest priority or the least number.
2. For the number of carbon atom, we add prefix as 'meth' for 1, 'eth' for 2, 'prop' for 3, 'but' for 4, 'pent' for 5, 'hex' for 6, 'sept' for 7, 'oct' for 8, 'nona' for 9 and 'deca' for 10.
3. A suffix '-ane' is added at the end of the name.
4. If two of more similar alkyl groups are present, then the words 'di', 'tri' 'tetra' and so on are used to specify the number of times these alkyl groups appear in the chain.

The given alkyl halide is:-

• $ClCH_2CH_2CH_2CH_3$
