Start Quiz
1.
Which reagent distinguishes ethanoic acid from ethanol?
Sodium metal
Sodium hydrogencarbonate
PCl5
Acidified dichromate
2.
What forms when ethanoyl chloride reacts with methylamine?
N-methylethanamide
Methyl ethanoate
Ethanamide
Ethylamine
3.
Why is alkaline hydrolysis of esters preferred for complete reaction?
It is faster
It uses a catalyst
The carboxylate ion cannot react back with the alcohol
It produces the free acid
4.
Which reducing agent converts propanoic acid into propan-1-ol?
NaBH4 in water
H2 without catalyst
Sn / HCl
LiAlH4 in dry ether
5.
Which pair of monomers can form a polyester?
Ethane-1,2-diol and hexanedioic acid
Ethene and propene
Hexane-1,6-diamine and hexanedioic acid
Ethanol and ethanoic acid
6.
Why do carboxylic acids form dimers in non-polar solvents?
Ionic bonding
Covalent bonding
Two hydrogen bonds between COOH groups
London forces only
7.
Which statement best describes Esterification?
An acid that only partially dissociates into ions in water.
The functional group -COOH, made of a C=O and an -OH on the same carbon.
A condensation polymer whose monomers are joined by ester links.
The reversible reaction of a carboxylic acid with an alcohol, catalysed by acid, to form an ester and water.
8.
Which statement best describes Polyester?
Alkaline hydrolysis of an ester (or fat) giving a carboxylate salt and an alcohol.
A condensation polymer whose monomers are joined by ester links.
The reversible reaction of a carboxylic acid with an alcohol, catalysed by acid, to form an ester and water.
A compound containing the -COCl group, e.g. ethanoyl chloride CH3COCl.
9.
Which statement best describes Hydrolysis?
A condensation polymer whose monomers are joined by ester links.
A compound containing the -COO- group, formed from an acid (or acyl chloride) and an alcohol.
Breaking a bond by reaction with water, often catalysed by acid or alkali.
An organic compound containing the carboxyl group -COOH.
10.
Which statement best describes Dimer?
Two molecules joined together, e.g. two carboxylic acid molecules held by hydrogen bonds.
Alkaline hydrolysis of an ester (or fat) giving a carboxylate salt and an alcohol.
An organic compound containing the carboxyl group -COOH.
The reversible reaction of a carboxylic acid with an alcohol, catalysed by acid, to form an ester and water.
