It forms a more stable primary carbocation

Bromide is a stronger nucleophile at carbon 1

It forms a more stable secondary carbocation

The reaction is free-radical, not electrophilic

No change

The solution turns from orange to green

A white precipitate forms

The orange colour is decolourised

Hot sodium hydroxide dissolved in ethanol

Warm aqueous sodium hydroxide, with the reaction carried out under reflux

Cold dilute sodium hydroxide solution dissolved in plenty of water

Aqueous silver nitrate solution warmed gently with the halogenoalkane

1-chlorobutane, because the C-Cl bond is the most polar of the four bonds

1-iodobutane, because the C-I bond has the lowest bond enthalpy

1-fluorobutane, because fluorine is the most electronegative of the halogens

All of the halogenoalkanes react at exactly the same rate as each other

Propanal

Propanoic acid

Propanone

Propene

Ethene and steam passed over a heated phosphoric acid catalyst under pressure

Bromoethane warmed with aqueous sodium hydroxide solution under reflux

Ethanol warmed with acidified potassium dichromate(VI) as the oxidising agent

Ethanol and ethanoic acid with a concentrated sulfuric acid catalyst

The molecular ion peak at the highest mass-to-charge ratio

The tallest (base) peak, which is always the most abundant fragment ion

The peak that appears at a mass-to-charge ratio of $m/z = 1$ in the spectrum

The fingerprint peak, the unique pattern of fragments below $m/z = 1500$

An alcohol, containing an -OH group only

A carboxylic acid (-COOH)

A ketone, containing a C=O group only

An alkane, containing only C-H single bonds
