Hybridization Of Atomic Orbitals

Question 1

Hybridization

Answer 1

Types of description for atomic orbitals used by atoms to share electrons

Question 2

How can molecules account for their exact nature

Answer 2

Adopting a set of atomic orbitals other than 2s or 2p

Mixing called hybridization

Question 3

Sp3 hybridization

Answer 3

One 2s orbitals and three 2p orbitals are combined to make four identical orbitals (4 bonding pairs —> 8 e-)
All 4 orbitals have the same shape
TETRAHEDRAL ARRANGEMENTS —> 109.5

Question 4

Degenerate

Answer 4

Same amount of energy

Question 5

What are the bonds sp3 hybridization leads to

Answer 5

4 sigma (single bonds) can take 4 extra electrons

Question 6

Sp2 hybridization

Answer 6

Mixing of one 2s orbital and 2/3 2p orbitals

Each a set of 3 identical sigma bonds (can take 3e- extra)

Question 7

Energy for sp2 orbitals

Answer 7

One extra p orbital is higher in energy than the rest

The extra p orbital is ready for a pi bond (double)

Question 8

What is the secondary bound for sp2

Answer 8

Occurs by sharing one electrons above and below the sigma

Question 9

What does a double bond consist of

Answer 9

Of one sigma bond

One pi bond where one is below no one is above

Question 10

Sp hybridization

Answer 10

Mixing one s orbital with 1/3 p orbital
2 2p orbitals available for further bonding
2 sp orbitals forms single bonds
Extra 2p orbital form pi bonds

Question 11

Geometry of sp hybridization

Answer 11

Provide linear 180

Question 12

Dsp3 hybridization

Answer 12

Mixing of one s obital, one d and 3 p

Accounts for the molecules that exceed the octet rule

Question 13

Geometry of dsp3

Answer 13

Trigonal bipyrimidal angle 90 between x-y plane

120 between x-x plane

Question 14

D2sp3 hybridizations

Answer 14

Mixing one s, 3 p, 2d

Accounts for the molecules with 6e- pairs
