A strong acid together with one of its soluble salts

A weak base mixed with an excess of pure water

A weak acid and its conjugate base

A strong base together with an equal strong acid

It must lie within a closed carbon ring structure

It must form part of a carbon-carbon double bond

It must carry at least one hydroxyl OH group

It must be bonded to four different groups

Tollens reagent

2,4-DNPH

Bromine water

Sodium hydroxide

It has no double bonds at all within its ring structure

It is a fully saturated molecule with only single bonds

Substitution preserves the stable delocalised ring

Addition reactions would release far too much energy to occur

It is inherently far less stable than benzene to begin with

It contains a greater number of carbon atoms than benzene does

It contains an extra reactive double bond sitting outside the main ring

A lone pair on the oxygen raises the electron density of the ring
