Valence Bond Theory
Hybridization
Bond Properties
200

Valence bond theory is 

Referring to the overlapping of orbitals when bonding different atoms, also known as the hybridization of atomic orbitals


200

What is hybridization 

Orbitals in the molecule are different from those on individuals atoms

200

What is the order of bond length greatest to least?

Single, double, triple

400

Two electrons of opposite spin can 

Accommodate the overlapping orbitals 

400

How many lobes are overlapping in a pi bond?

four lobes

400

How do you differentiate a cis-isomer from a trans-isomer?

A cis-isomer occurs on the same side of a molecule's double bond while the trans-isomer occurs on the opposite side of the molecule's double bond.

600

The strength of the bonds depend on 

The overlapping, shape, and direction of the orbitals 

600

What must occur for sp3 hybridization 

The process of mixing one s atomic orbital with 3 p atom

600

What is another way of thinking of bond enthalpy and why?

An energy storage center because when a chemical reaction occurs energy would be required or released.

800

Why is the H-H electron cloud distorted?

The electrons have a higher probability of being found between the two nuclei

800

What hybridization can you expect in the Lewis Structure that exceeds the octet rule?

A sp3d

How do you calculate the enthalpy change of any reaction?

  • ΔHrxn= ΣD (bonds broken) - ∑D (bonds formed)
