Question

(For each) Explain whether the following molecules will react in these conditions (and why):

A. (SN1) with AgNO3/EtOH, at room temperature

B. (SN1) with AgNO3/EtOH, at hot temperature (90C)

C. (SN2) with NaI/acetone, at room temperature

D. (SN2) with NaI/acetone, at hot temperature (50C)

(Please say Y (yes) or N (no) for each A-D for each molecule. Thanks!)

(feel free to skip the crotyl molecule)

Cl 1-chlorobutane cchexane Br 2 1-bromobutane CI -butylchloride /~ 2-chlorobutane crotyl chloride Cl CH2CI benzyl chloride 2-bromobutane Br 8r bromobenzene -Br bromocyclopentane Figure 7-1.

Explanation / Answer

As primary alkyl halide favours SN2 due to less steric hinderence and tertiary amine favours SN1 reaction due to formation of stable tertiary carbocation intermediate, the following options are:

1- D (Cl- is weaker leaving group)

2-C

3-B

4-A

5-A

6-B

7-A

7-B (2nd part)

8-A

9- not possible with out any activating substituent
