Alkyl Halides and Alcohols

Most alkyl halides are insoluble in H 2 O Smaller alcohols however are very soluble in H 2 O because these molecules can engage in hydrogen bonding with H 2 O molecules For larger molecules however the polar OH group is overwhelmed by the nonpolar alkyl part of

Alcohol Reaction with HCl HBr and HI Acids

What is the Mechanism of converting alcohols to alkyl halides? We are working with a substitution – the OH group is replaced with a halogen Therefore regardless of what alcohol is used (1 o 2 o or 3 o) the principle of this substitution is to convert the OH into a good leaving group and kick it out by the halide ion (S N 2) or the nucleophile may attack after the OH
