Basic Concepts of Organic Chemistry - Organic Chemistry

Question 1

What is the difference between saturated & unsaturated hydrocarbons?

Answer 1

Saturated have single C-C bonds only, unsaturated have C=C double bonds.

Question 2

What is meant by the term homologous series?

Answer 2

Series of organic compounds with the same functional group & general formula whose successive members differ by the addition of a -CH₂ group.

Question 3

What is meant by the term functional group?

Answer 3

The part of an organic molecule that is responsible for the characteristic reactions of that molecule.

Question 4

What are aliphatic hydrocarbons?

Answer 4

Carbon atoms joined in branched or unbranched chains, or joined in non-aromatic rings e.g. hexane.

Question 5

What are alicyclic hydrocarbons?

Answer 5

Carbon atoms joined in non-aromatic ring structures e.g. cyclohexane.

Question 6

What are aromatic hydrocarbons?

Answer 6

Carbons atoms in a benzene ring e.g. benzene.

Question 7

What is an alkyl gorup?
