    Hi guys,

    This is a question on a sheet I was given about nucleophilic substitution and the 2 possible mechanisms (SN1 and SN2).

    Is anyone able to help me?

    Thanks

    2-bromobutane has a chiral centre and is a secondary haloalkane. It can react via both sN1 and sN2 mechanisms.

    The sN1 reaction will give rise to a racemic mixture of enantiomers, as it proceeds via a planar structure and can then be attacked by the incoming nucleophile from either side.
