S _ N 1 reactions are favoured by
Options
- Anon-polar solvents
- Bbulky groups on the carbon atom attached to the halogen atom
- Csmall groups on carbon atom attached to the halogen atom
- DNone of the above
Correct answer
B. bulky groups on the carbon atom attached to the halogen atom
Step-by-step solution
Bulky groups on the carbon atom attached to the halogen atom will hinder attack by S _ N 2 mechanism due to steric hindrance and hence, would favour S _ N 1 mechanism.
