Question

how many minimum carbons required for chain isomerism and position isomerism in alkanes​

Answer 1

Answer:

3 Carbons

Explanation:

4 carbonSo, in an alkane chain, it'd require at least 3 carbons. Example: Propyl bromide (1) and isopropyl bromide (2) are constitutional isomers. Minimum 4 carbon atoms are required for alkenes to show position isomerism( if there is no functional group other than the double bond).
