1
Q
3 rules or resonance structures
A
- Obeys octet rule
- Fewest formal charges
- Neg charge on most electronegative atoms
2
Q
Nucleophile trends
A
1 When comparing the same atom a negative charge shows stronger nucleophile
2 atoms In the same period, Less electronegative or more nucleophilic
3. Nucleophilicity increases with size in a column
3
Q
Good leaving groups
A
1.Resonance stabilized
2. Week bases
3.  neutral Leaving groups (h2O, ROH)
4
Q
Bad bases
A
- Strong bases
- Acid catalysis can make a bad leaving group a good leaving group.
5
Q
4 factors of molecular stability
A
- Resonance
- Induction
- Size
- Electronegativity
6

3200-3600
8
Q
Ir peak for c=c
A
1650
9
