Start Quiz
1.
Which halogenoalkane hydrolyses fastest?
1-chlorobutane
1-bromobutane
1-iodobutane
1-fluorobutane
2.
Why is ethanol added in the hydrolysis practical?
It is a catalyst
It acts as a common solvent
It oxidises the halide
It is the nucleophile
3.
What is the purpose of NaHCO3(aq) when purifying 2-chloro-2-methylpropane?
To neutralise remaining acid
To dry the product
To act as a catalyst
To oxidise impurities
4.
To make propanoic acid from propan-1-ol you should:
distil immediately
use limited oxidant
add bromine water
heat under reflux with excess oxidant
5.
Acidified BaCl2 gives a white precipitate. Which ion is present?
CO32-
Cl-
NH4+
SO42-
6.
Colour change of acidified dichromate when it oxidises an alcohol:
Green to orange
Orange to green
Purple to colourless
Colourless to yellow
7.
Which statement best describes Hydrolysis?
The breaking of a bond by reaction with water (or hydroxide ions).
Tests that identify which ions or functional groups are present, rather than how much.
An anhydrous salt such as anhydrous Na2SO4 or CaCl2 that removes water from an organic liquid.
Heating a reaction mixture with a vertical condenser so volatile components condense and return, allowing prolonged heating.
8.
Which statement best describes Nucleophile?
Heating a mixture so the most volatile component vaporises and is condensed and collected separately.
Heating a compound in a flame to identify metal ions from the colour emitted.
Tests that identify which ions or functional groups are present, rather than how much.
A species with a lone pair of electrons that attacks an electron-deficient carbon.
9.
Which statement best describes Separating funnel?
Heating a compound in a flame to identify metal ions from the colour emitted.
Apparatus used to separate two immiscible liquid layers.
A species with a lone pair of electrons that attacks an electron-deficient carbon.
An alcohol in which the carbon bearing the OH is bonded to three other carbon atoms.
10.
Which statement best describes Distillation?
An anhydrous salt such as anhydrous Na2SO4 or CaCl2 that removes water from an organic liquid.
Tests that identify which ions or functional groups are present, rather than how much.
Heating a mixture so the most volatile component vaporises and is condensed and collected separately.
The breaking of a bond by reaction with water (or hydroxide ions).
