A group of atoms which are responsible for the characteristics of a particular compound
1 of 16
Homologous Series -
A series of compounds with the same functional group and with similar characteristics
2 of 16
Alkenes - Properties and combustion -
C n H 2n / Only incomplete combustion to produce a smokier yellow flame / More reactive because of C=C bond / Unsaturated
3 of 16
Addition of Alkenes -
Diatomic compounds can be reacted with alkenes / The double carbon bond breaks to allow for the addition of the other atoms
4 of 16
Alkenes and Halogens -
Alkenes can react with halogens / Bromine water is a common test / It starts yellow / The bromine is split and reacts with the double carbon bond - Dibromo...ene / Yellow water turns colourless
5 of 16
Alkenes and Hydrogen -
They can react using a nickel catalyst / The reaction forms an alkane
6 of 16
Alkenes and Steam / water -
Alkenes react with steam to make alcohol / Requires high temperatures / The reaction is reversible
7 of 16
Making Alcohols - Fermentation
Alcohols can me made naturally with fermentation / Yeast uses glucose to produce ethanol and carbon dioxide
8 of 16
Alcohols -
-OH functional group / Soluble in water / Flammable
9 of 16
Carboxylic Acids -
-COOH functional group / Weak acids
10 of 16
Esters -
Based on a carboxylic acid / The normal carboxylic acid functional group is altered / The final -H is replaced by a hydrocarbon / E.G. Ethyle Ethanoate
11 of 16
Uses of Alcohols -
Ethanol is used in alcoholic drinks / Good solvents / Can be used as a biofuel
12 of 16
Reactions of Alcohols - Combustion
Very flammable / Burn with clean blue flame because they contain oxygen
13 of 16
Reactions of Alcohols - Group 1 metals
Alcohols react with group 1 metals to produce a metal alkoxide and water
14 of 16
Reactions of Alcohols - Oxidation
Combustion can oxidise alcohols / Can be oxidised using oxidising agents (potassium dichromate)
15 of 16
Carboxylic acids -
Turn universal indicators orag
