Question

2 ethane 1 pentene Structure and
Bond line.

Answer 1

Pentene: Pentene is a compound with five carbon atoms and a double bond. The 'ene' part refers to a double bond somewhere in the molecule. The chemical formula for pentene is: C5 H10. The most basic five carbon chain will have a chemical formula of: C5 H12, but as pentene has a double bond, it has two less hydrogen atoms.

Ethane: Ethane is a colorless, odorless, and flammable gas with a chemical formula of C2H6; it has two carbon (C) atoms and six hydrogen (H) atoms. By looking at its chemical structure, the two carbon atoms are bonded together and there are three hydrogen atoms attached to each carbon atom.
