12. Introduction to Organic Chemistry

Propane (C₃H₈) is a component of liquified petroleum gas. Draw a structural formula for propane. (Hint: Carbon makes four bonds.)

Methylamine (CH₅N) is a gaseous compound with a fishy smell. Draw this molecule using structural formula.

Draw the straight-chain isomer with the formula (b) C₉H₂₀.

There are two branched-chain isomers with the formula C₇H₁₆, where the longest chain in the molecule is six carbons long. Draw them.
