Question

Be sure to answer all parts.

Consider the following S_N2 reaction:

What happens to the reaction rate in each of the following instances?

Part 1:

The leaving group is changed from Br^− to I^−.

The reaction is

not changedfasterslower

.

Part 2:

The solvent is changed from acetone to

CH₃CH₂OH

.

The reaction rate

increasesdecreasesstays the same

.

Part 3:

The alkyl halide is changed from

CH₃(CH₂)₄Br

to

CH₃CH₂CH₂CH(Br)CH₃.

The reaction rate

increasesdecreasesstays the same

.

Part 4:

The concentration of ^−CN is increased by a factor of 9.

Reaction rate will

decreaseincrease

by a factor of

.

Part 5:

The concentration of both the alkyl halide and ^−CN are increased by a factor of 3.

Reaction rate will

increase (It will increase this part is right)

_{by a factor of ............?????? I got this one wrong. What is it? ( THIS IS THE ONLY ONE I GOT WRONG IN All THE PARTS)}
