Section 5 review

VSEPR

100

Each group around a central atom are located as far away as possible to do this? 

what is minimize repulsions?

200

these are maximised which defines a molecules 3D shape

what are bond angles?

300

order these from least to greatest repulsion: 

LP and BP 

BP and BP 

LP and LP 

BP and BP < LP and BP < LP and LP

400

triple and double bonds place more of this on one side of the central atom than single bonds

what is electron density? 

EDG

100

has 8 domains?

what is octahedral?

200

this has 2 LP and 2 BP 

what is tetrahedral 

300

lower-energy conformations result from havcing non-bonding electrons in these positions? 

what are equatorial positions? 

400

this molecule has BOTH <90 and <120 degree bond angles 

what is trigonal bipyramidal 

MG

100

the molecular domain geometry of methane (CH4)

what is tetrahedral

200

this molecule exhibits bond angles of <<109.5 

what is bent 

300

this molecule has 3 lone pairs and 2 bonding pairs

what is linear?

400

the amount of bonding pairs and lone pairs in an see-saw

what is 4 BP and 1 LP?

Hybridization

100

the hybridization scheme for the carbon in HCOOH

what is sp2?

200

this term describes electrons at the same energy level, it is achieved through hybridization. 

what is degenerate orbitals or degeneracy? 

300

the number of domains from a central atom with an sp3d2 hybridization scheme.

what is 6 domains? 

400

There is a complex molecule with 3 triple bonds, 2 double bonds, and 1 single bond. How many pi bonds and sigma bonds are in the molecule? 

8 pi bonds and 6 sigma bonds
