Question

(a) In the following reaction, determine the substrate, nucleophile and mechanism?

Part (a) options


(a)The substrate is a primary halide. The nucleophile is propyl bromide. The mechanism is a SN1 mechanism.

(b) Incorrect. The nucleophile is water not propyl bromide.

(c) The substrate is a primary halide. The nucleophile is water. The mechanism is a SN2 mechanism.

(d) The substrate is a tertiary halide. The nucleophile is propyl bromide. The mechanism is a SN1 mechanism.

(e) Incorrect. Primary halides generally do not proceed through SN2 mechanisms.

(f) The substrate is a tertiary halide. The nucleophile is water. The mechanism is a SN1 mechanism.


(g) The substrate is a tertiary halide. The nucleophile is water. The mechanism is a SN2 mechanism.

(h) The substrate is a tertiary halide. The nucleophile is propyl bromide. The mechanism is a SN2 mechanism.

Why does this reaction proceed so slowly?

The nucleophile is very weak. This causes a slow reaction.

The substrate has very low reactivity. This causes a slow reaction.

The nucleophile is very strong. This causes a slow reaction.

Bromide ion is not a good leaving group. This causes a slow reaction.


(a)The substrate is a primary halide. The nucleophile is propyl bromide. The mechanism is a SN1 mechanism.

H2O + HBr Br OH

Explanation / Answer

statement C is correct

Substance is primary halide , water is nucleophile and reaction proceeds through Sn2 mechanism

Reaction goes slowly because

Nucleophile is weak
