Question

Explain SN1 reaction and mention the conditions favoring it.​

Answer 1

Explanation:

The four main conditions to determine which mechanism, out of a

S

N

1

reaction and an

S

N

2

reaction, are as follows:

the type of carbocation that would be formed (via

S

N

1

)

the extent of steric hindrance

the strength of the attacking nucleophile

the type of solvent used

Explanation:

In this explanation, I shall cite the nucleophilic substitution of the molecule with molecular formula

C

3

H

7

Br

, undergoing nucleophilic attack by the

OH

−

(hydroxide) complex ion.

Also remember that nucleophilic substitution reactions are in competition with elimination reactions, but the sets of conditions to favour each of these two reaction types are different to those that cause one type of nucleophilic substitution to be favoured.
