Question

2.Draw a structural formula for 2,3-octene (C8H16) which has a double bond between the second and third carbon in the chain. According to our lessons, what class of compound is it? How do you know?

Answer 1

First, we have to draw eight carbons and a double bond between carbon two and carbon three, always complying with bonding the carbon four times:

The double bond is between carbon 2 and 3 (the number indicates it in red) and its color is blue. This class of compound is called: alkene because an alkene is a hydrocarbon with one or more carbon-carbon double covalent bonds.
