Some Families Of Organic Compunds

Question 1

Chloroalkane

Answer 1

Compound in which one or more of the hydrogen atoms in an alkane molecule have been replaced by chlorine atoms

Question 2

Functional group

Answer 2

Atom or group of atoms which is responsible for the characteristic properties of an organic compound or a series of organic compounds

Question 3

Primary Alcohol

Answer 3

One where the carbon atom joined to the OH group is attached to only one other carbon atom

Question 4

Secondary alcohol

Answer 4

One where the carbon atoms joined to the OH group is attached to two other carbon atoms

Question 5

Tertiary alcohol

Answer 5

One where the carbon atom joined to the OH group is attached to three other carbon atoms

Question 6

Condensation reaction

Answer 6

Chemical reaction in which two molecules combine to form a larger molecule with the loss of a smaller molecule such as water

Question 7

Steam distillation

Answer 7

Separation process used to isolate compounds at temperatures below their decomposition temperatures. It is carried out by bubbling steam through the material and distilling off the immiscible liquids

Question 8

Principle of steam distillation

Answer 8

Is that a mixture of two immiscible liquida boil at a temperature that is below that of the boiling point of each of the individual liquids. The hot mixture of water vapour and oil is passed through a condenser and the distillate that is collected contains a mixture of oil and water

Question 9

Emulsion

Answer 9

Dispersion of small droplets of one liquid in another liquid which is not soluble

Question 10

Liquid liquid extraction

Answer 10

Technique in which two immiscible liquids are separated using a solvent in which one of the components of the mixture has a higher solubility than the other, ie: the organic solvent is removed from the emulsion by dissolving the organic component in an organic solvent
