13.2 - Nucleophilic substitution in halogenoalkanes Flashcards
(8 cards)
1
Q
Uses of nucleophilic substitution
A
form aminos, alcohols and carboxylic acids
2
Q
Halogenoalkanes reaction with ammonia
A
3
Q
Halogenoalkanes with cyanide ions reaction
A
4
Q
halogenoalkanes reaction with aqueous sodium/potassiumm hydroxide:
A
5
Q
Why are Fluoro-compounds unreactive?
A
the strength of the C-F bond is too strong
- going down the reactivity increases but strength decreases
6
Q
Nucleophilic Substitution example reaction:
A
7
Q
Examples of nucleophiles (what do the nucleophiles replace in a halogenoalkane):
A
8
Q
what are nucleophiles?
A
a negatively charged ion or atom which has a partially negative charge
* has a lone pair of electrons or unpaired electron which can be used to form a covalent bond
* lone pair is in an electronegative atom
