Editing Answer To CP Review HW For LDS Of Covalent Bonding Substance

ChemistryWiki | RecentChanges | Preferences

Part I

ai) Lewis Dot Structure (LDS), picture that shows what element is sharing valence electrons (ve-) and how many ve- are not shared around each atom. 
aii) VSPER - changes LDS into shapes/geometry of substance 
 
aiii) Hybridization - theory behind concepts 
 
 
b) Molecular compounds (MC) and polyatomic ions 
 
c) No LDS is based on pairs of ve- 
 
d) Number of Column (counting Left to Right not including D and F block elements). 
 
e) After bonding (determining shared and lone pair for each element) All element want 8 ve- around then except H ( 2ve-), Be (4 ve-) and B (6 ve-)
 
fi) Same outside atoms (non-central atom) 
fii) Two different types of bonds (i.e. 2 single and 1 double bonds) 
 
Part II 
 
1a) Total # of ve- = 18ve- 
1b) You draw 
1ci) N is central atom and 1 LP 
1cii) 1 double and 1 single bond (Resonance structure and need [ ] since it is ion) 
 
2a)Total # of ve- = 18ve- 
2b) You draw 
2ci) O is central atom and 2 LP 
2cii) 2 single bonds 
 
3a)Total # of ve- = 26ve- 
3b) You draw 
3ci) S is central atom and 1 LP 
3cii) 3 single bonds (need [ ] since it is ion 
 
4a)Total # of ve- = 32ve- 
4b) You draw 
4ci) C is central atom and 0 LP 
4cii) 4 single bonds
