Molecule Structure – Organic Chemistry Quiz 9
The key terms of this Organic Chemistry course include Molecule Structure.
Below is the Lewis structure of the ammonia (NH3) molecule.
Count the number of bonding pairs and the number of lone pairs around the top hydrogen atom.
Answer
Bonding pairs: 1
Lone pairs: 0
In each of the molecules drawn below one chemical bond is colored red. Decide whether this bond is likely to be polar or not. If the bond is likely to be polar, write down the chemical symbol for the atom which will have more negative charge.
Answer
Arrange the highlighted bonds in the table below in decreasing order of polarity. That is, pick 1 for the most polar bond, pick 2 for the next most polar bond, and so on.
Answer
Arrange the highlighted bonds in the table below in decreasing order of polarity. That is, pick 1 for the most polar bond, pick 2 for the next most polar bond, and so on.
