• the lone pair of electrons on the nitrogen atom in aniline is not involved in resonance

• benzylamine has a higher molecular mass than aniline

• the lone pair of electrons on the nitrogen atom in benzylamine is delocalised

Which of the following pairs are correctly matched?

	Reactants	Products
(i)	RX+ AgOH (aq)	RH
