Answer 1

The group of organic compounds which differ by CH2 are known as homologous Series

Answer 2

Answer:

All answers are given in the characteristics.

Characteristics of organic compounds are as follows:

• These are mad up of only a few elements C, H, O, N, S, X. (Cl, Br, I)

• These involve covalent bonds.

• These are generally gases or liquids.

• They have low melting and boiling points.

• They are combustible.

• They show molecular reactions.

• They show isomerism.

• These are non - conductors of electricity.

• There are generally insoluble in water but soluble in organic solvents.
