Chapter 10

Question 1

Steps to determine geometry

Answer 1

1. Draw lewis structure
2. Find arrangement of electron pairs
3. Find arrangement of bonding pairs
4. Determine geometry based on bonding pairs

Question 2

Hybridization

Answer 2

Mixing of two or more atomic orbitals to form a new set of hybrid orbitals

Question 3

Molecular orbital theory

Answer 3

Bonds are formed from intersection of atomic orbitals to form molecular orbitals

Question 4

Bonding molecular orbital

Answer 4

Has lower energy and greater stability than the atomic orbitals from which it was formed

Question 5

Antibonding molecular orbital

Answer 5

Has a higher energy and lower stability than the atomic orbitals from which it was formed

Question 6

How to determine molecular geometry

Answer 6

1. Draw lewis diagram

2. Count number of lone pairs and bonded atoms

Question 7

Bent shaped has

Answer 7

One or more loan pairs on central atom

Question 8

Linear

Answer 8

Either a 2 atom molecule or if its three then has no loan pairs on central atom

Question 9

In geometry atoms want to do what?

Answer 9

Get far away from each-other (repel out)

Question 10

Five atom molecule

Answer 10

Tetrahedral and 109.5 degrees

Question 11

Four atom molecule

Answer 11

Trigonal planar and 120 degrees or if theres a double bond 122 degrees

Question 12

Three atom molecule

Answer 12

Bent and 119 degrees

Question 13

Trigonal planar vs. trigonal pyramidal

Answer 13

In trigonal planar, there are no lone pair electrons in the central atom. But in trigonal pyramidal there is one lone pair at the central atom
