When an unsymmetrical alkene undergoes electrophilic addition you often get a major and minor product. What would the major product be when propene reacts with hydrochloric acid? Why is this?

The major product would be 2-chloropropane whilst the minor product would be 1-chloropropane. This is because the more stable secondary carbonation is formed as an intermediate. This is easy to show with a m...

Name and draw the mechanism by which benzene reacts with ethanoyl chloride in the presence of a catalyst. Also explain why benzene undergoes a substitution reaction, rather than an addition reaction.

Electrophilic substitution. (drawn) AlCl 3 + CH 3 COCl --> AlCl 4 - + CH 3 CO + (drawn) Then the electrophile CH 3 CO + attracts electrons from benzene's delocalised ring to form an intermediate, that the...
