Structure And Bonding Flashcards
1
Q
Predict the bond angle in an F2O molecule. Explain your answer.
A
- 104.5
- 2 lone pairs and 2 bonded pairs
- Lone pairs repel more than bonded pairs
2
Q
What is the shape of an ammonium ion (NH4+) ?
A
Tetrahedral
3
Q
NH3 hydrogen bonding
A
Draw hydrogen bond from lone pair to hydrogen atom
4
Q
Graphene delocalised electrons
A
The fourth electron of each carbon atom is delocalised
5
Q
Why doesn’t pure water conduct electricity?
A
There are no free charge carriers in water
6
Q
Explain why the boiling point increases from sodium to aluminium
A
- The number of delocalised electrons increases
- Ionic radius decreases
- Metallic bonding strengthens
7
Q
