Chapter 5: 5.3 The SN2 Reaction

Question 1

Describe:

SN2 reaction

Answer 1

Bimolecular
* Two species are present in the rate equation

Question 2

True or False:

Only changing the concentration of one of the two species in a SN2 reaction affects the rate

Answer 2

False, changing the concentration of either species changes the rate

Question 3

Explain:

The etymology behind SN2 Reaction

Answer 3

Substituion Nucleophilic Bimolecular (2) Reactions

Question 4

State:

The rate formula for SN2 Reactions

Answer 4

Rate = k [substrate] [nucleophile]

Question 5

Where does an SN2 reaction occur?

Answer 5

Occurs between a strong nucleophile and an electrophile with little steric hinderance

Question 6

Describe:

SN2 reaction process

Answer 6

Direct substitution of the leaving group with the nucloephile, in a single step

Question 7

A strong nucleophile is usually…

Answer 7

Negatively charged

Question 8

What is the mechanism of an SN2 reaction?

Answer 8

Happens in a single step via a crowded transition state

Question 9

True or False:

A transition state can be spectroscopically observed

Answer 9

False, it cannot

Question 10

What happens in the SN2 reaction if you make a chiral product?

Answer 10

You will get a single product with inversion of configuration
