Hydrocarbons

Question 1

What are hydrocarbons

Answer 1

Hydrocarbons are organic compounds composed of Carbon and hydrogen only.

Question 2

Properties of carbon

Answer 2

1. The exceptional ability of carbon atoms to Catenate
2. The ability of carbon to form single, double or triple covalent bonds.
3. Different arrangement of the atoms within a molecule produces a variety of compounds
4. The ease with which carbon combines with hydrogen, oxygen, nitrogen and the halogens

Question 3

The two main classes of Hydrocarbons are:

Answer 3

1. Aliphatic Hydrocarbon: Aliphatic Hydrocarbon is a hydrocarbon compound containing carbon and hydrogen joined together in straight chains either acyclic or cyclic. They may be saturated or unsaturated.
2. Aromatic Hydrocarbon: It combines single and double bonds in one. It is a derivative of benzene.

Question 4

What is homologous series

Answer 4

This is a family of Organic compounds which follow a regular

structural pattern in which each successive member differs in its molecular formula by a –CH2- group .

Question 5

Alkyl

Answer 5

This includes all univalent groups derived from the ALKANE by the loss of
a Hydrogen atom. It determines the physical properties

Question 6

Functional group

Answer 6

This is an Atom, a radical or bond common to a homologous series
and determines the main chemical properties of the series.
