Lecture 20

Question 1

Lone pairs

Answer 1

Repels the most and decreases angle between bonding pair

Question 2

Unpaired electron (AKA) radical

Answer 2

Repels less and increases angle between bonding pair

Question 3

Double bonds

Answer 3

Greater electron density than single bond and repels single bonds

Question 4

Polarity

Answer 4

There is a difference in electronegativity

Question 5

Nonpolar

Answer 5

There is no difference in electronegativity

Question 6

Cis isomer

Answer 6

• Polar
• atoms are on the same side
• boiling pt is higher

Question 7

Trans isomer

Answer 7

• Non polar
• Same atoms are on opposite sides
• Boiling pt is lower
