Question

But-1-ene and But-2-ene are examples of ____________.

Options

• chain isomers

• position isomers

• functional group isomers

• geometric isomers

Answer 1

But-1-ene and But-2-ene are examples of position isomers.

Explanation:

The isomerism which is due to the difference in the position of double bond in the same carbon chain is called position isomerism.

\[\ce{\underset{(But-1-ene)}{^δCH3 - ^γCH2 - ^βCH = ^αCH2}}\]

\[\ce{\underset{(But-2-ene)}{^δCH3 - ^γCH = ^βCH - ^αCH3}}\]
