Answer 1

Answer:

CH3CH=CHCH3 name of the compound

2-butene

Answer 2

Answer:

But - 2 ene (or) 2- Butene

Explanation:

Start numbering from either end such that double bond gets lowest number.

CH3 - CH = CH - CH3

1          2       3       4

4 carbons are there. So name starts with but- .

Check for any functional groups. This compound has no funnctional groups. So, there is no need for prefix naming.

Double bond is from 2nd to 3rd carbon. So, the name should be But - 2 -ene according to lowest sum rule, not But - 3 ene.

2 - Butene is also accepted name.
