Question

Q. What is the decreasing order of reactivity
SN2 reaction ?

—
1 - Bromo - 2,2-dimethypropane
1- Bromopentane
1-Bromo-2-methylbutane​

Answer 1

Answer:

1 - Bromo-2-dimenthypropane 1 - bromopentane 1 - bromo-2-methylbutane

Explanation:

the SN2 reactions are sensitive to steric hindrance. greater the steric hindrance tot he attacking nucleophile, lesser will be reactivity.

Answer 2

Explanation:

The decreasing order of reactivity SN2 reaction is:

• 1 - Bromo -2-methylbutane
• 1 - Bromo -2,2-dimethypropane
• 1 - Bromopentane

I hope this is helpful..
