A carbon bonded to four different atoms or groups

A carbon forming a double bond to a neighbouring carbon atom within the chain

A carbon in a benzene ring

A carbon bonded to two identical groups

Benzene readily decolourises bromine water at room temperature without any catalyst present

All six carbon-carbon bonds are equal in length

Benzene has a low boiling point

Benzene reacts by addition like an alkene

$\text{HNO}_3$

$\text{NO}_3^-$

$\text{NO}_2^+$

$\text{NO}^+$

Phenol has a higher molecular mass, so its bonds to hydrogen are weaker and break more readily

Phenol contains more oxygen atoms

Ethanol cannot lose a proton at all

The phenoxide ion delocalises its negative charge into the ring, stabilising it

Tollens' reagent gives a silver mirror only with the aldehyde

Both decolourise bromine water and turn it from orange to colourless within a few seconds

Both give a violet colour with iron(III) chloride

Only the ketone reduces dichromate

Propanal

Propan-2-ol

Propan-1-ol

Propanoic acid

Amide

Ester

Acyl chloride

Acid anhydride

The nitrogen atom in phenylamine carries no lone pair at all and so cannot accept a proton from water

It is a stronger acid

The alkyl group withdraws electrons

The nitrogen lone pair is delocalised into the benzene ring, so it is less available

A zwitterion with no net charge

A positively charged cation, because both the amino and carboxyl groups are fully protonated here

A negative ion

A neutral un-ionised molecule

It has two hydrogens

It is adjacent to three equivalent $\text{CH}_3$ hydrogens, so $n+1 = 4$

It is adjacent to the OH only

A $\text{CH}_2$ group always couples to the solvent and is therefore split into four separate peaks
