Give the structure corresponding to the iupac name 2−sec−butyl−4,4−diethylnonanoic acid

The structure of 2-Sec-butyl-4,4-diethylnonanoic acid is attached below,

The structure was drawn using following information.

1) First, the parent chain was identified, as the parent name is specified at the end of the name, so it was found to be nonanoic acid. The nonane specifies the number of nine carbon atoms and -ic acid specifies that the parent compound is carboxylic acid with nine carbons.

2) Secondly, the substituents were added as follow,

                       a) At alpha position (2nd carbon next to carbonyl carbon) a sec-butyl group was added.

                       b) At carbon 4, two ethyl groups were added, as the number 4,4 shows double substitution of same substituent.
