Question

Structure and iupac name for isopentyl

Answer 1

Answer: IUPAC name of isopentyl is 3-methylbutyl.

Explanation: Prefix iso is used for those alkanes in which one methyl group is attached to the next to end carbon atom (second last) of the continuous chain.

For IUPAC nomenclature, the longest carbon chain is chosen from the end which contains a functional group. The carbons which do not get a number are called as substituents.

In naming first the name of the substituent is written by writing the number of carbon to which it attached, followed by the word root of the longest chain of carbon followed by the functional group. Thus the name is 3-methyl butane.
