Arrange the following in order of decreasing tendency towards `S_(N^(2))` reaction :
`{:(underset("(I)")(CH_(3)CH_(2)CH_(2)CH_(2)Cl)", "underset("(II)")(CH_(3)CH_(2)CHClCH_(3)",")),(underset("(III)")((CH_(3))_(2)CHCH_(2)Cl)", "underset("(IV)")((CH_(3))_(3)C-Cl)):}`

A

`I gt III gt II gt IV`

B

`III gt IV gt II gt I`

C

`II gt I gt III gt IV`

D

`IV gt III gt II gt I`

Text Solution

Verified by Experts

The correct Answer is:
A
The decreasing order of reactivity towards `S_(N)2` reaction is
`underset((I))(CH_(3)CH_(2)CH_(2)Cl) gt underset((III))((CH_(3))_(2)CHCH_(2)Cl) gt underset((II))(CH_(3)CH_(2)CHClCH_(3)) gt underset((IV))((CH_(3))_(3)C Cl)`
This is because of increasing steric hindrance.
