Flashcards in Topic 11: Valence Bond Theory, Video C: Sp2 and Sp Hybridization (Sigma and Pi Bonds) Deck (10):
1

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

A pi bond sharing 2 electrons.

2

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

Parallel. Perpindicular form no bonds.

3

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

sp2.

4

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

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

5

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

One sigma bond and one pi bond.

6

Triple bond is composed of which bonds?

1 sigma and 2 pi bonds.

7

To examine the bonding of a molecule first determine what?

The lewis structure.

8

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

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

9

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

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

10

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

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