Question #fcc45

Answer 1

The longest carbon chain containing functional groups has got `7` carbon atoms,

`"So stem name is " to "hept"`

Senior of the two functional group is `-COOH` having suffix name `"oic acid"`

Other junior functional group present is `-CHO` in C-7 . So its prefix name `"oxo"` is to be added with locant `7`.
At C-6 a methyl group `-CH_3` is linked . Its name is to be added with locant `6` in the prefix.
Finally the compound is saturated one so suffix due to senior functional group. `-COOH` is to be followed by suffix `"ane"`

Hence the IUPAC name will be

`color(red)("6-methyl-7oxoheptanoic acid")`
