Alcohols

Alcohols are not hydrocarbons as they contain an oxygen atom. 
They have the functional group ‘-OH‘ in their molecule. 

They have the general formula: CnH₂n₊₁OH
If (n = 3), the compound would be:
C₃H₂₍₃₎₊₁OH = C₃H₇OH

Every alcohol’s name ends in ‘-ol’.

An alcohol’s prefix always changes according the number of carbon atoms present in the compound. 

Some common alcohols:
