Question

Draw 2-methylpentanoic acid. Include all the hydrogen atoms in your structural formula.

Answer 1

Concepts and reason

Nomenclature of organic compounds is done with certain rules assigned by IUPAC (International Union of Pure and Applied Chemistry). Generally, the IUPAC name pattern consists of 3 parts. They are:

I.Root name

II.Prefix

III.Suffix

Fundamentals

The three parts of an IUPAC name are root name, prefix, and suffix.

The longest chain tells about the root name.

The prefix tells the position and name of the substitutions present on the longest chain.

The suffix tells the functional group present in the structure.

${\rm{IUPAC name = prefix + word root + suffix}}$

The given IUPAC name is 2-methylpentanoicacid

${\rm{IUPAC name = prefix + word root + suffix}}$

Word root of the compound is pent

Prefix in the IUPAC name is 2-methyl

Suffix in the IUPAC name is Oic acid

The word root is pent, which indicates that the longest carbon chain has five carbon atoms.

The prefix is 2-methyl, which indicates that the methyl substituent is at the second position of the carbon chain.

The suffix is oic acid, which indicates the carboxylic acid functional group.

Therefore, the structure of the compound is drawn below.

The structural formula of the compound is shown below.
