Card preview (10)

#1
Front (Question)

Mechanism from an alkane to a haloalkane

Back (Answer)

free radical sub

#2
Front (Question)

Stage 1 - initiation

Back (Answer)

breaking of the halogen bond to form 2 atoms with a dot (unpaired electron)

#3
Front (Question)

Why is UV light required for initiation?

Back (Answer)

it provides energy to break the halogen bond

#4
Front (Question)

Stage 2 - propagation steps (general)

Back (Answer)

step 1; alkane + halogen radical –> alkyl radical + hydrogen halide step 2; alkyl radical + halogen –> haloalkane (desired product) + halogen radical

#5
Front (Question)

Stage 3 - termination

Back (Answer)

2 free radicals join to form a stable molecule with no unpaired electrons.

#6
Front (Question)

What is a nucleophile?

Back (Answer)

an electron pair donor

#7
Front (Question)

Name the mechanism, reagents and conditions for haloalkane to Alcohol

Back (Answer)

nucleophilic sub reagent: NaOH conditions: aqueous

#8
Front (Question)

Name the mechanism, reagents and conditions for haloalkane to nitrile

Back (Answer)

nucleophilic sub reagent: KCN conditions: ethanol

#9
Front (Question)

Name the mechanism, reagents and conditions for haloalkane to amine

Back (Answer)

nucleophilic sub reagent: excess NH3 conditions: ethanol + heat

#10
Front (Question)

Name the mechanism, reagents and conditions for haloalkanes to alkenes

Back (Answer)

Elimination reagent: NaOH conditions: ethanol solvent
