CH3 - CH2 - CH - CH2 - CH = CH2

Answer 1

The name of that product is 1-nonene.

The sufix ene is because it is an alkene, which comes from the fact that it has a double bond.

The prefix none is because it has 9 carbon.

And the use of number 1 is because the double bond is in the carbon number 1.
