Question 0

Other name for free radical substitution

Answer 0

Photochemical radical substitution

Question 1

3 equations used in the manufacture of ammonium sulfate (NH4)2SO4

Answer 1

Stage 1: CH4 + 2H2O –> 4H2 + CO2
Stage 2: 3H2 + N2 –> 2NH3
Stage 3: NH3 + H2SO4 –> (NH4)2SO4

Question 2

Overall reaction equation for photochemical radical substitution

Answer 2

CH4 + 4Cl2 —> CCl4 + 4HCl

Question 3

What gives rise to geometric isomerism?

Answer 3

Lack of free rotation

Question 4

Reforming

Answer 4

Heating a large molecule in the presence of a catalyst in order to restructure the carbon framework e.g the conversion of a straight chain hydrocarbon into a branched chain

Question 5

Reaction mechanism

Answer 5

The detailed pathway that shows how a reactant molecule is converted into a product molecule

Question 6

Geometric isomers

Answer 6

Compounds with the same molecular formula but different geometric configuration due to a double bond or ring

Question 7

Why are carboxylic acids acidic?

Answer 7

The carboxylate ion (without H+) is stabilised by resonance

Question 8

Resonance

Answer 8

The process by which a molecule can exist in more than one form which differ only by the position of electrons. The charge is delocalised.
