The bulky tert-butyl substituent blocks the back side of the carbon bonded to the bromine to nucleophilic attack, making an SN2 reaction difficult. An SN1 reaction cannot occur because it would require the formation of an unstable primary carbocation. 2. It cannot undergo an E2 reaction, because the B-carbon is not bonded to a hydrogen. It cannot undergo an E1 reaction, because that would require the formation of a tertiary carbocation.Fill in the table below indicating what is important in each category for an SN1 reaction and an SN2 reaction.
