The reaction of toluene with chlorine in the presence of ferric chloride gives mainly

Explanation

Methylamine dissolves in water to give methylammonium hydroxide, which ionises to give methylammonium and hydroxide ions.
`underset("Methylamine")(CH_(3)overset(..)NH_(2))+H_(2)Oiffunderset("Methylammonium hydroxide")([CH_(3)NH_(3)]^(+)OH)iff[CH_(3)NH_(3)]^(+)+OH^(-)`
Due to the formation of `OH^(-)`, ions they can precipitate out iron aluminium, chromium etc., from their salts.
`[CH_(3)NH_(3)]^(+)OH^(-)+FeCl_(3)rarrFe(OH)_(3)darr+CH_(3)NH_(3)Cl`
Ferric hydroxide being unstable can be considered as hydrated ferric oxide.
`2Fe(OH)_(3)rarrFe_(2)O_(3)+3H_(2)O`
