Front (Question)

Homologous series

Back (Answer)

Organic compounds in the same functional group, each member differs by CH2 e.g alkenes

Front (Question)

Products of complete combustion of an alkene

Back (Answer)

Carbon dioxide and water

Front (Question)

What is more reactive, alkanes or alkenes? Why? Where do the reactant molecules go?

Back (Answer)

Alkenes due to their double C bond Reacting molecules join to the alkene across the double bond

Front (Question)

Hydrogenation of alkenes Reactant? Conditions? Creates? Example?

Back (Answer)

H2 150 oc, Ni catalyst Saturated hydrocarbon (alkane) C2 H4 + H2 —> C2 H6

Front (Question)

Halogenation of alkenes Reactant? Conditions? Example?

Back (Answer)

I2, Br2, Cl2 Aqueous solution C2 H4 + Br2 —> C2 H4 Br2

Front (Question)

Hydration of alkenes Reactant? Conditions? Creates? Example?

Back (Answer)

H2O steam High temp and pressure, catalyst Alcohol C2 H4 + H2O —> C2 H5 OH

Front (Question)

Alcohols Displayed formula is similar to ? End in?

Back (Answer)

Alkane, remove H and add OH -OH

Front (Question)

Carboxylic acids How to create the displayed formula? End in?

Back (Answer)

Alkane, remove all H from end and add a double bond to O and an OH -COOH

Front (Question)

Esters How to create the displayed formula? End in?

Back (Answer)

Replace the H in carboxylic with a hydrocarbon -COO-

#10

Front (Question)

Products of ethanol + ethanoic acid methanol + propanoic acid

Back (Answer)

ethyl ethanoate methyl propanoate

#11

Front (Question)

3 Uses of alcohols

Back (Answer)

Ethanol in alcoholic drinks, solvents in perfumes, fuels

#12

Front (Question)

Combustion of alcohols Key fact? Flame? Products?

Back (Answer)

Flammable Creates a blue flame Carbon dioxide, water

#13

Front (Question)

Natural way alcohols are made? Word equation? Reactant? Catalyst? Ad and dis?

Back (Answer)

Fermentation Glucose–> ethanol + carbon dioxide Glucose from plants Yeast Low temp, takes longer

#14

Front (Question)

Industry way alcohols are made? Word equation? Reactant and from where? Catalyst? Ad and dis?

Back (Answer)

Hydration of ethenes Ethene + steam–> ethanol Ethene from crude oil Phosphoric acid Takes shorter, high temp

#15

Front (Question)

Alcohol reaction with sodium Forms? Observations? Methanol + sodium–> Butanol + potassium–>

Back (Answer)

Forms hydrogen and salt Fizzes, gets smaller Sodium methoxide + hydrogen Potassium butoxide + hydrogen

#16

Front (Question)

Oxidation of ethanol Reactants? Products?

Back (Answer)

Ethanol + acidified potassium dichromate Ethanoic acid + water

#17

Front (Question)

2 key properties of carboxylic acids? Carboxylic acid + metal carbonate forms? and observation?

Back (Answer)

Soluble in water, weak acids Salt, water, carbon dioxide, fizzes

#18

Front (Question)

Weak acid def?

Back (Answer)

An acid that partially ionises in solution to form H+ ions

#19

Front (Question)

Formula equation for ethanoic acid in solution? Carboxylic acid reacting with metal carbonate compared to HCl?

Back (Answer)

CH3COOH⇌ CH3COO- + H+ Carboxylic has higher pH, lower conc of H+ ions, slower reaction with metal carbonate than strong acids

#20

Front (Question)

How to make esters equation What are esters used for?

Back (Answer)

carboxylic acid + alcohol ⇌ ester + water when using an acid catalyst Perfumes and flavourings as they are fragrant
