Molecular Geometry and Hybridization Types

Question 1

Linear

(Electron groups, Lone pairs, Angle, and Polarity)

Answer 1

• Electron groups: 2
• Lone pairs: 0
• Angle: 180°
• Polarity: Either (use EN difference)

(2 bound atoms will always be linear)

Trigonal Planar

(Electron groups, Lone pairs, Angle, and Polarity)

Answer 2

• Electron Groups: 3
• Lone Pairs: 0
• Angle: 120°
• Polarity: Nonpolar

Question 3

Bent

(Remember: There are two types!!)

Answer 3

• Electron Groups: 3
• Lone Pairs: 1
• Angle: 105°
• Polarity: Polar

(May also have 4 Electron Groups and 2 Lone Pairs)

Question 4

Tetrahedral

(Electron groups, Lone pairs, Angle, and Polarity)

Answer 4

• Electron Groups: 4
• Lone Pairs: 0
• Angle: 109.5°
• Polarity: Nonpolar

Question 5

Trigonal Pyramidal

(Electron groups, Lone pairs, Angle, and Polarity)

Answer 5

• Electron Groups: 4
• Lone Pairs: 1
• Angle: 107°
• Polarity: Polar
