Question

why are C1 to C4 alkane gases and c5 to c 17 liquids​

Answer 1

Answer:

THE LIGHT HYDROCARBONS-methane (C1), ethane (C2), propane (C3), and the butanes (C4), either in the gas phase or liquefied, are primarily used for heating, motor fuels, and as feedstocks for chemical procession

points?

A straight chain alkane will have a boiling point higher than a branched chain alkane because of the greater surface area in contact with other molecules. Branching makes molecules more compact thus reduces the surface area
