Four main reaction types of alcohols

Combustion, oxidation, elimination (dehydration), substitution

Complete combustion products of alcohols

Carbon dioxide and water

Common oxidising agent for alcohols

Acidified potassium dichromate(VI) - \ceK2Cr2O7/H2SO4\ce{K2Cr2O7/H2SO4}

Colour change when alcohol oxidation occurs

Orange dichromate(VI) to green chromium(III)

Conditions to form aldehyde from primary alcohol

Acidified dichromate with distillation (gentle heating)

Conditions to form carboxylic acid from primary alcohol

Excess acidified dichromate with reflux

Product when secondary alcohol is oxidised

Ketone

What happens when tertiary alcohol meets oxidising agent?

No reaction; solution remains orange

Dehydration of alcohols: conditions and product type

Conc. \ceH2SO4\ce{H2SO4} or \ceH3PO4\ce{H3PO4}, reflux; forms alkenes

In alcohol substitution, -OH is replaced by what?

Halogen atom (forming haloalkane)
