Question

Which will react faster towards sn2 displacement, 1-bromopentane or 2- bromopentane and why?

Answer 1

Answer: 1-Bromopentane will reacts faster towards Sn2 displacement because 1-Bromopentane is 1° alkyl hallide and 2-Bromopentane is 2° alkyl hallide and according to the Sn2 reactivity series, [Ch₃°>1°>2°>3°]

The 1° alkyl hallide gives Sn1 faster than 2° alkyl hallide.

Answer 2

Answer:

1-bromopentane.

Explanation:

SN² reaction is single step reaction.its order of reaction in alkyl halyde is 1°›2°›3°(means 1° is More fast react in SN² ) so, 1-bromopentane is fast react than 2-bromopentane.
