Question

What is the name of this compound??

Answer 1

3-ethylhept-2-ene

Explanation:

Since the longest chain is in a straight line, having 7 carbons and a double bond ;

So that's what it makes heptene since the double bond comes at the 2nd position , so it should be hept-2-ene .

Also, the ethyl group present at the 3rd position , so it should be;

3-ethyl-2-heptene or 3-ethylhept-2-ene ( to indicate that the double bond ''ene'' is present at the 2nd position ).

Hope this Helps.. ^_^
