Ch. 9: Substitution and Elimination Reactions of Alkyl Halides

Question 1

What kind of elements can undergo substitution and/or elimination reactions?

Answer 1

The families of group 2 on the periodic table, they all have an electronegative atom or an electron-withdrawing group attached to a sp3 carbon

Question 2

What is a substitution reaction?

Answer 2

the electronegative atom or electron-withdrawing group is replaced by another atom or group

Question 3

What is an elimination reaction?

Answer 3

the electronegative atom or electron-withdrawing group is eliminated, along with a hydrogen atom from an adjacent carbon

Question 4

What order reaction is a nucleophilic substitution reaction?

Answer 4

a second order, the rate depends linearly on the concentration of each of the two reactants

Question 5

What does SN2 mean?

Answer 5

S=substitution
N=nucleophilic
2=bimolecular

Question 6

As the alkyl group of an SN2 reaction get larger, what happens to the rate of the substitution reaction with a given nucleophile

Answer 6

the rate of the sub rxn with a given nucleophile decreases
