Chapter 6

Question 1

hybridization

Answer 1

a mash-up of valence orbitals to have unpaired valence e- in proper orientations for bonding (minimizing e-/e- repulsions)

Question 2

3 group hydridization

Answer 2

sp2

Question 3

4 group hybridization

Answer 3

sp3

Question 4

5 group hybridization

Answer 4

dsp3

Question 5

6 group hybridization

Answer 5

d2sp3

Question 6

sigma bond

Answer 6

is a single bond (first connection) and is always a result from hydridized orbitals

Question 7

pi bonds

Answer 7

is the extra layer of bonding (past the single bond) to create double and triple bonds, these always result from non-hybridized orbitals

Question 8

double bonds consists of…

Answer 8

1 sigma and 1 pi bonds

Question 9

triple bonds consists of…

Answer 9

1 sigma and 2 pi bonds

Question 10

linear combinations of atomic orbitals/molecular orbital theory (MO theory)

Answer 10

• describes the energetics of bonding between elements
• all orbitals are combined between two elements. Each combination of 2-orbitals results in 2 new orbitals, a bonding orbital (good) and an antibonding orbital (bad)

Question 11

bond order

Answer 11

predicts if a molecule can exist
BO=0 molecule cannot exist
BO>0 molecules can exist
Formula: # of e- in bonding-#of e- in antibonding/2
