Question

Iupac name of h3c-ch=c-ch2ch3

Answer 1

In this molecule, the longest carbon chain consists of five carbon atoms.

So, the root word is "pent".

A double bond is present, so it is an alkene and the suffix is "ene".

The double bond should get the lowest numbering.

The numbering begins from the left and the double bond is numbered by 2.

So, the IUPAC name of this molecule will be: Pent-2-ene
