New cards

Formal charge formula

FC = valence e⁻ − lone pair e⁻ − 1/2 bonding e⁻

2
New cards
3
New cards

Best Lewis structure

Full octets, lowest formal charges, negative charge on more electronegative atom

4
New cards
5
New cards

Resonance

Same atom skeleton, different electron placement

6
New cards
7
New cards

Electron domain

Any single bond, double bond, triple bond, or lone pair around central atom

8
New cards
9
New cards

2 electron domains

Linear, 180°

10
New cards
11
New cards

3 electron domains

Trigonal planar, 120°

12
New cards
13
New cards

4 electron domains

Tetrahedral, 109.5°

14
New cards
15
New cards

1 lone pair on tetrahedral arrangement

Trigonal pyramidal, slightly less than 109.5°

16
New cards
17
New cards

2 lone pairs on tetrahedral arrangement

Bent, less than 109.5°

18
New cards
19
New cards

Lone pairs and bond angles

Lone pairs repel more strongly, so bond angles shrink

20
New cards
21
New cards

Polar molecule

Bond dipoles do not cancel

22
New cards
23
New cards

Nonpolar molecule

Bond dipoles cancel due to symmetry
