Name the following haloalkane H H H I I I H-C-C -C-Br I I I H H H
1 bromo- propane
What property does the C-Br bond have
The C-Br bond is polar so it can be attacked by a nucleophile
List 3 nucleophiles
NH3 + CN + OH
what type of reaction do haloalkanes undergo
Nucleophilic Substitution + Nucleophilic Elimination
Name the following Nitrile H H I I H -C-C-CN I I H H
propanenitrile
which bond from C-F to C-I is most reactive
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
What are the conditions for substitution vs elimination
Substitution= aqueous in water room temp Elimination= Aqeous in ethanol, under reflux, room temp
