VB Theory Is Poorly Suited to Polar Molecules Such as HCl

question 13

Multiple Choice

• B) VB theory assumes bonds form only between unpaired electrons in atomic orbitals
• C) VB theory can't predict p bonds
• D) VB wavefunctions always have even parity with respect to inversion
• E) VB wavefunctions do not contain any ionic states
