Question 1

Volatility

Answer 1

Is the ease that a liquid turns into a gas. Volatility increases as boiling point decreases.

Question 2

Reflux

Answer 2

Is the continual boiling and condensing of a reaction mixture to ensure that the reaction takes place without the contents of the flask boiling dry.

Question 3

Esterification

Answer 3

Is the reaction of an alcohol with a carboxylic acid to produce an ester and water.

Question 4

Dehydration

Answer 4

Is an elimination reaction in which water is removed from a saturated molecule to make an unsaturated molecule.

Question 5

Hydrolysis

Answer 5

Is a reaction with water or aqueous hydroxide ions that breaks a chemical compound into two compounds.

Question 6

Nucleophilic substitution

Answer 6

Is a type of substitution reaction in which a nucleophile is attracted to an electron-deficient centre or atom, where it donates a pair of electrons to form a new covalent bond.

Question 7

Limiting reagent

Answer 7

Is the substance in a chemical reaction that runs out first.

Question 8

Molecular ion

Answer 8

Is the positive ion formed in mass spectrometry when a molecule loses an electron.

Question 9

Fragmentation

Answer 9

Is the process in mass spectrometry that causes a positive ion to split into pieces, one of which is a positive fragment ion.

Question 10

Radical

Answer 10

Is a species with an unpaired electron.

Question 11

Electrophile

Answer 11

Is an electron pair acceptor

Question 12

Nucleophile

Answer 12

Is an electron pair donor.
