Question 9

Hydrogen Bonds

Answer 9

Strongest Dipole Dipole Force. H with FON. Stronger than Dipole Dipole normal and LDF.

Question 10

Hybridization

Answer 10

single = double = triple = lone pair = x
each (x-1) is the number for the sp.

EX: Linear = x = 2 = sp

Question 11

Pi and Sigma Bonds

Answer 11

Single = sigma
Double = sigma + pi
Triple = sigma + 2pi

Question 12

Nonpolar vs Polar

Answer 12

Vectors cancel out in nonpolar.

Question 13

Relationships High Yield

Answer 13

More EN Difference ∝ More Ionic Bond ∝ More Bond Stregnth ∝ More Polarity ∝ Higher Melting and Boiling

More Polarity ∝ More Bond Stregnth is important

Question 14

Relationships Low Yield 1

Answer 14

More IMF Stregnth ∝ Lower Vapor Pressure ∝ Higher Boiling

Question 15

Relationships Low Yield 2

Answer 15

More electrons ∝ Higher Boiling Point ∝ Higher Melting Point

Question 16

Formal Charges

Answer 16

Most Stable Lewis has…

1. 0 Formal Charge on all
2. Most EN atom having negative formal charge

0 formal on all is more stable than negative on most EN.
