What is a hydrocarbon?

Hydrocarbons are compounds that contain carbon atoms and hydrogen atoms only.

1

What makes a saturated hydrocarbon different to an unsaturated hydrocarbon?

Saturated hydrocarbons have singe bonds whilst unsaturated carbons have a double bond

2

What are the three different types of formula used to represent hydrocarbons?

Molecular formula
Full Structural formula
Shortened structural formula

3

Define a homologous series.

A homologous series is a series of compounds with similar chemical properties which can be represented by a general formula.

4

Is a cycloalkane a saturated or unsaturated hydrocarbon?

Saturated, it contains only single bonds.

5

What is an isomer?

Isomers are compounds with the same molecular formula but different structural formula.

6

What formula can be used to calculate the energy of a fuel?

Eh = cm/\T

7

What is an exothermic reaction?

An exothermic reaction is a reaction in which energy is released.

8

What is an endothermic reaction?

An endothermic reaction is a reaction in which energy is taken in.
