The `IUPAC` name of `CH_(3)-overset(CH_(3))overset(|)(CH)-overset(O)overset(||)(C )-CH_(2)CH_(2)OH` is

Options

A. (1) `4`-methyl-`3`-oxopentan-`1`-ol
B. (2) `2`-merthyl-`5`-hydroxypentan-`3`-one
C. (3)`1`-hydroxy-`4`-methylpentan-`3`-one
D. (4) hexan-`1`-ol-`3`-one

Answer

C

Explanation

It is a polyfunctional compound. The principal function is the group, thus, it should be named as an alkanone. The numbering of the parent chain is done so as to giev the lowest possible number to the `C` atom of the carbonyl group :
`overset(5)(C)H_(3)-underset(1-"Hydroxy-4-nethylpentan-3-one")(underset(CH_(3))underset(|)overset(4)(CH)-overset(O)overset(||3)(C)-overset(2)(C)H_(2)overset(1)(C)H_(2)OH)`
