VBT MBT

Question 1

VBT developed by

Answer 1

Linus Pauling

Question 2

MOT developed by

Answer 2

Robert D Mulliken

Question 3

When is VB most efficient to use (3)

Answer 3

1. generally the method of choice to provide a qualitative visual picture of molecular structure and bonding
2. useful for molecules made of many atoms
3. provides a good description of bonding for molecules in their ground or lowest energy state

Question 4

When is MO most efficient to use (3)

Answer 4

1. more quantitive picture
2. essential to describe molecules in higher energy excited states
3. NO and O2 only for MO theory

Question 5

The idea that_______ is the basis for VBT

Answer 5

bonds are formed by the overlap of atomic orbitals

Question 6

cis and trans

Answer 6

do not interconvert because the pi bond is has to break

Question 7

cis is when

Answer 7

double bond middle with the same on each top/bottom side

Question 8

trans is when

Answer 8

double bond middle with opposite atoms (top= AB bottom=AB) that are the same diagonally.
