Basic Concepts Of Organic Chemistry

Question 1

Define an aliphatic compound

Answer 1

A compound that contains carbon and hydrogen in straight chains, branched chains or non-aromatic rings.

Question 2

Define an alicyclic compound

Answer 2

An aliphatic compound arranged in non-aromatic rings

Question 3

Define a saturated compound

Answer 3

Contains single bonds only

Question 4

Define an unsaturated compound

Answer 4

Contains at least one double bond

Question 5

Define homologous series

Answer 5

Same functional group
Each successive member differs by a CH2

Question 6

Define molecular formula

Answer 6

The actual number of atoms of each element in a compound

Question 7

Define empirical formula

Answer 7

The simplest whole number ratio of atoms of each element in a compound

Question 8

When describing organic compounds, what features should be described?

Answer 8

•Longest carbon chain in the molecule
•Branched carbon chains
•Position of a functional group on a carbon chain
•Multiple functional groups in a molecule
•Multiples of the same functional group on a carbon chain

Question 9

Define structural isomerism

Answer 9

Same molecular formula but different structural formula

Question 10

Define chain isomerism

Answer 10

Molecules with the same molecular formula but a different length of carbon chain

Question 11

Define position isomerism

Answer 11

Molecules with the same molecular formula and same length of carbon chain, however the functional group is attached at different positions along the chain

Question 12

Define functional group isomerism

Answer 12

Molecules with the same molecular formula but a different functional group
