    Define the word 'bulkiness'.

    Do you mean more heavy?

    The molar mass of (CH3)3CBr is heavier.

    nope it just says: 'Rate of reaction is favoured by the bulkiness of the alkyl substituent (controlled by the stability of the Carbocation intermediate) in SN2 reaction''

    (CH3)3CBr is more bulky in terms of groups or for nucleophillic substitution!

    What's the difference between the two? Replacing a H with a methyl group.

    Which is more bulky, a methyl group or a H? A methyl group.

    As the H is a single atom attached to the central carbon it is less bulky than when 3 carbons ( each with 3 H also attached) are attached to the central carbon!

    thanks! So how does this determine the stability of the carbocation intermediate in an SN1 reaction?

    Yes it does! The bulky groups mean the reaction has to be SN1 as it needs to be a two step process!
