Question

A)

1. +NaOH HBrHo +HBrH20 Br BF3 - BF3 g SN1 Nucleophilic substitution h SN2 Nucleophilic substitution a = Proton transfer b Lewis acid/base c Radical chain substitution Identify the mechanism by which each of the reactions above proceeds from among the mechanisms listed. Use the letters a-i for your answers. d = Electrophilic addition e E1 Elimination f E2 Elimination 2.

B)

For the A, it is not 1:f, 2:d , it is wrong

Answer 1

Answers:

A) 1 f 2 b

B) 1 h 2 b

For the A part 1 E2 elimination occurs with strong base NaOH and alkyl halide.

2 ether will act as Lewis base by giving its lone pair to Lewis acid BF3. Therefore Lewis acid/base reaction.

For the B part 1 Intramolecular SN2 reaction occurs.

2 Lewis acid base reaction occurs between Lewis base aldehyde and lewis acid TICl4.
