Structure

Question 1

What does VSEPR recognise?

Answer 1

The importance of lone pairs, multiple bonds and electronegativity in determining geometry and isomerism in main group molecules

Question 2

What is the first step of VSEPR?

Answer 2

Decide the connectivity of the molecule

Question 3

What is the second step of VSEPR?

Answer 3

Draw a lewis structure for the molecule ignoring lone pairs

Question 4

What is the third step of VSEPR?

Answer 4

Count the number of electrons in the valence shell of the central atom

Question 5

What is the fourth step of VSEPR?

Answer 5

Choose an appropriate shape that places the electron pairs as far apart as possible

Question 6

What is the 5th step of VSEPR?

Answer 6

Assign the bonding pairs and lone pairs of electrons to the appropriate vertices of these geometries by taking account of different spatial requirements

Question 7

What is the 6th step of VSEPR?

Answer 7

Adjust the angles from their ideal values to accommodate the different spatial requirements
