1
Q

A
reagent: bromine
conditions: room temp
2

conditions: room temp
3

conditions: room temp
4
Q
electrophile
A
e pair acceptor
5
Q
alkyl
A
e releasing
6
Q
positive inducing effect
A
alkyls push e away within a covalent bond
7
Q
order of stability
A
1) tertiary - 3 alkyl groups surrounding carbon (most stable)
2) secondary - 2 alkyl groups surrounding carbon
3) primary - 1 alkyl groups surrounding carbon (least stable)
8
Q
Explain why there is an attraction between a C=C double bond and Br2
A
C=C electron rich
Br-Br becomes polarised
δ+ Br attracted to C=C
