Topic 11: Valence Bond Theory, Video C: Sp2 and Sp Hybridization (Sigma and Pi Bonds)

Question 1

When p orbitals interact constructively they overlap side to side and form what kind of bond?

Answer 1

A pi bond sharing 2 electrons.

Question 2

For maximum pi bonding: p orbitals are in what position to one another when they overlap?

Answer 2

Parallel. Perpindicular form no bonds.

Question 3

The sigma bonds forms the head on overlap of which hybrid orbitals?

Answer 3

sp2.

Question 4

In the formation of a pi bond the uhybridized p orbitals lie where?

Answer 4

Above and below the plane and overlap to form the pi bond.

Question 5

In the formation of a pi bond, double bonds occur from the combination of what bonds?

Answer 5

One sigma bond and one pi bond.

Question 6

Triple bond is composed of which bonds?

Answer 6

1 sigma and 2 pi bonds.

Question 7

To examine the bonding of a molecule first determine what?

Answer 7

The lewis structure.

Question 8

The second step in examining the bond in a molecule is to determine the molecular geometry by doing what?

Answer 8

Count the number or VESPR (valence electron shell pair repulsion) pairs which determines whether it is linear, triginol planar, etc.

Question 9

In examing the bonding of a molecule what is the third step in examination.

Answer 9

Determine which hybrid orbitals the atom is using such as sp or sp2 etc.

Question 10

In examining the bonding of a molecule, what is the fourth step.

Answer 10

Determine the kind of bond that is formed. (Sigma or Pi).
