New cards

assigning formal charge

draw Lewis structure, determine each atom’s neutral valence, assign each atom ½ of bonding e- + lone pairs, calculate

2
New cards

formal charge calculation

FC = valence e- - lone pair e- - ½ (bonding e-)

3
New cards

better to have all FC =_ than any FC ≠ _

0

4
New cards

have arrangement with the smallest in magnitude ≠0 _

FCs

5
New cards

preferable when adjacent FCs are

zero or of opposite sign

6
New cards

preferable to have more negative FCs on

more electronegative atoms
