5.2 hybridization and the localized e- model

Question 0

sigma bond

Answer 0

a type of covalent bond in which an e- pair is shared in an area centered on a line running between the atoms

Question 1

sp2 hybridization is formed from

Answer 1

one 2s and two 2p orbitals

Question 2

what type of bond forms by a shared e- pair in the space above and below a line joining the atoms in the parallel p orbitals

Answer 2

pi bonds

Question 3

which type of bind is formed from orbitals whose lobes point toward each other?

Answer 3

sigma bond

Question 4

pi bond results from (parallel/perpendicular/shared) orbitals

Answer 4

parallel

Question 5

what does a double bond consist of?

Answer 5

one sigma bond where the e- pair is located directly between the atoms and one pi bond where the shared air occupies the space above or below the sigma bond

Question 6

Answer 6

sp2 hybridized

Question 7

two hybrid orbitals arranged at 180 degrees requires

Answer 7

sp hybridization

Question 8

what does one s orbital and one p orbital create?

Answer 8

sp hybridization

Question 9

sp hybridization is always required with how many effective pairs?

Answer 9

2

Question 10

a set of 5 e- pairs around a given atom always requires a trigonal bipyramidal arrangement which in turn requires

Answer 10

dsp3 hybridization of that atom

Question 11

dsp3 hybridization is formed by

Answer 11

one d orbital

Answer 12

octahedrally

d2sp3 hybridization

Question 13

order the stops of the localized e- model

Answer 13
