Question 24

Molecular polarity

Answer 24

If dipoles cancel out

• Nonpolar if all bonds are nonpolar without a lone pair
• linear always nonpolar
• usually lone pairs mean polar

Question 25

Hybridization

Answer 25

Count clouds and subtract one

Question 26

VSEPR theory

Answer 26

Valence Shell Electron Repulsion Theory

• Charge clouds repel each other due to Coulombic repulsion
• Terminal atoms move as far away as possible from one another as possible
• Results in distinctive geometric shapes
