Answer 1

Explanation:

To Find -

• Which compound in the following pairs will reacts faster in SN2 reaction with -OH.

Solution :-

1)

1-Bromo ethane or 1-fluoro ethane

Here,

1-bromo ethane reacts faster in SN2 reaction because bromine is good leaving group (L.G.) as compared to Flourine. So, here Br leave easily. So, it goes under SN2 reaction fastly.

2)

3-chloro pentane or 1-chloro pentane

Here,

1-chloro pentane reacts faster in SN2 reaction because it's a 1°-Halide.

Reactivity order of SN2 reaction :-

• 1° > 2° > 3°

Reactivity order of SN1 reaction :-

• 3° > 2° > 1°
