Question
Match the molecule to the correct molecular shape.
- CH₂Cl₂
- SO₂
- NF₃
- SO₃
[1]
[2]
[3]
[4]
Solution
Sure, here are the molecular shapes for each molecule:
-
CH2Cl2 (Dichloromethane): This molecule has a tetrahedral shape. The carbon atom is at the center of the molecule with the hydrogen and chlorine atoms surrounding it. The bond angles are approximately 109.5 degrees.
-
SO2 (Sulfur Dioxide): This molecule has a bent or V-shaped geometry. The sulfur atom is in the middle with the oxygen atoms on either side. The bond angle is less than 120 degrees due to the presence of a lone pair of electrons on the sulfur atom.
-
NF3 (Nitrogen Trifluoride): This molecule also has a trigonal pyramidal shape. The nitrogen atom is at the center with the fluorine atoms surrounding it. The bond angles are less than 109.5 degrees due to the presence of a lone pair of electrons on the nitrogen atom.
-
SO3 (Sulfur Trioxide): This molecule has a trigonal planar shape. The sulfur atom is in the center with the oxygen atoms surrounding it. The bond angles are 120 degrees.
