Sagot :
The chemical formula for the alkene pentene is C5H10. Pentene is an unsaturated hydrocarbon that is made of five carbon atoms and ten hydrogen atoms.
Answer:
Pentene is a compound with five carbon atoms and a double bond. If we break apart the name of the compound, then the structure makes sense. The 'pent-' part means 'five' and refers to the longest chain of five carbon atoms. The 'ene' part refers to a double bond somewhere in the molecule.
