Make up the structural formulas of the following hydrocarbons: a) 3-ethyl-heptene-2; b) 3,3-dimethylpentene-1; c) 3-methyl-4-tylhexene-2.

1. Hepten-2 contains 7 carbon atoms, the double bond is between 2 and 3 carbon atoms. Draw an ethyl group from 3 carbon atoms.

2. Pentene-1 – 5 carbon atoms, a double bond between 1 and 2 carbon atoms, two methyl groups at 3 atoms.

3. Hexene-2 – 6 carbon atoms, double bond between 2 and 3 carbon atoms, methyl group at 3 atoms, ethyl group at 4 atoms.
