Answer:
See image below
Explanation:
You can start by drawing molecules taking into account the following factors:
Then the initial molecule should be ethylene, and we have 3 missing carbons, 2 of them would let us follow the 3rd rule and we have the 2-Butene and we are missing 1 carbon, that atom cannot be as a substituent of any carbon forming the double bond because there wouldnt be any stereoisomers, then it should be connected with a substituent carbon giving us the 2-Pentene
