2.6 Halogenoalkanes Flashcards
1
Q
How can halogenoalkanes be made?
A
- radical substitution
- electrophilic addition
2
Q
Why is the C-Cl bond polar?
A
Cl more electronegative than carbon therefore pulls carbon closer to it
3
Q
Why are halogenoalkanes susceptible to nucleophilic attack?
A
The polar C-C bond (delta + and delta -)
4
Q
What reagents/conditions are needed for nucleophilic substitution?
A
Aqueous NaOH and heating
5
Q
How do you test for iodine in an organic compound?
A
- heat with NaOH
- add nitric acid then silver nitrate
- yellow ppt
6
Q
Give a reason why something can be classed as a substitution reaction
A
Replacement of one functional group by another
7
Q
Halogenoalkane to alkene
A
- NaOH in alcohol
- elimination
