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.
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
