Answer 2

Answer: Butan-2-one

Explanation:

The IUPAC nomenclature is given as follows:

Select the longest possible carbon chain.

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.

The numbering is done in such a way that the functional group gets the lowest number. A suffix '-one' is added at the end of the name for functional group ketone after the position of the functional group.

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.

Hence, the name for given compound is butan-2-one.
