The diagram below shows the compound ethylbenzene.

Give the reagents and conditions required to convert ethylbenzene into 4-chloroethylbenzene.

Write an equation to show the formation of the electrophile for the reaction in part a).

Outline a mechanism for the reaction to form 4-chloroethylbenzene from ethylbenzene.

Draw the structure of the product obtained when ethylbenzene is heated with KMnO₄.

The diagram below shows the structure of benzaldehyde, the simplest aromatic aldehyde.

Write an equation for the formation of the electrophile from H₂SO₄ and HNO₃ in the nitration of benzaldehyde. 

Outline a mechanism for the formation of 3-nitrobenzaldehyde.

The diagram below shows the structure of methoxybenzene. Methoxybenzene reacts in a similar way to phenol.

Draw the structure of the organic product that would form when methoxybenzene is reacted with excess bromine.

Explain why the reaction of methoxybenzene with bromine does not require a halogen carrier.
