Bond Angles and Shapes

Question 1

2 bonding, 0 lone pairs (electrons)

Answer 1

-Linear
-180°

Question 2

2 bonding, 2 lone pairs (electrons)

Answer 2

-V-shape/bent
-104.5°

Question 3

3 bonding, 1 lone pair (electrons)

Answer 3

-Triangular pyramid
-107°

Question 4

3 bonding, 0 lone pairs (electrons)

Answer 4

-Trigonal planar
-120° (360/3; they repel each other)

Question 5

4 bonding, 0 lone pairs (electrons)

Answer 5

-Tetrahedral
-109.5°

Question 6

5 bonding, 0 lone pairs (electrons)

Answer 6

-Trigonal bipyramidal
-90° & 120°

Question 7

6 bonding, 0 lone pairs (electrons)

Answer 7

-Octahedral
-90°

Question 8

Change in the bonding/lone

Answer 8

The same amount of electrons (bonding or lone)- change in lone:bonding +/- 2.5°
Eg. 4 bonding, 0 lone: 109.5°
3 bonding, 1lone 107° (-2.5°)
2 bonding, 2 lone 104.5° (-2.5°)
