Unit 2 Haloalkanes

Question 1

Name the following haloalkane H H H
I I I
H-C-C -C-Br
I I I
H H H

Answer 1

1 bromo- propane

Question 2

What property does the C-Br bond have

Answer 2

The C-Br bond is polar so it can be attacked by a nucleophile

Question 3

List 3 nucleophiles

Answer 3

NH3 + CN + OH

Question 4

what type of reaction do haloalkanes undergo

Answer 4

Nucleophilic Substitution + Nucleophilic Elimination

Question 5

Name the following Nitrile H H
I I
H -C-C-CN
I I
H H

Answer 5

propanenitrile

Question 6

which bond from C-F to C-I is most reactive

Answer 6

C-F reacts slower than C-I because as you go down the bonds the bonds become weaker (lower bond enthalpy) so they are easily broken so become more reactive

Question 7

What are the conditions for substitution vs elimination

Answer 7

Substitution= aqueous in water room temp Elimination= Aqeous in ethanol, under reflux, room temp
