Electrophiles, nucleophiles, leaving groups

Question 1

SN2

Answer 1

Nucleophile attacks from back

Question 2

SN1

Answer 2

LLG than NA

Question 3

E2

Answer 3

Base steals positively charged spot

Question 4

E1

Answer 4

Base included

Question 5

Hydrohalogenation

Answer 5

H goes to anti mark, halo goes to mark

Question 6

Acid catalyzed hydration

Answer 6

H+ transfer, nuclear attack, H+ transfer (?)

Question 7

Oxymercuration demurcuration

Answer 7

OH at anti mark,.

Question 8

Wgat does hydroboration oxy use?

Answer 8

BH3, THF, H2O2, NaOH

Question 9

Hydroboration oxy

Answer 9

Antimark addition of H2O, mark addition of H across 2x bond, syn addn. 2 BH3 bonds together

Question 10

Catalytic Hydroboration

Answer 10

Addition of H2 across double bond gets rid of it

Question 11

Halo and halohydrin

Answer 11

Cl2 and Br2 are added across double bond. Double bond grabs 1, then positive charge recruits another.

Question 12

Halo and halohydrin f done in nucleuophilic solvent

Answer 12

, nucleophile may be added (so BR/H2O can have Br and OH added. OH would be mark.)
