A)three single bonds and one lone pair
B)three single bonds and two lone pairs
C)triple bond and two lone pairs
D) triple bond and one lone pair
Under which of the following circumstances would the molecular geometry be the same as the electron geometry?
A) identical terminal atoms
B) no lone pairs on the central atom
C) presence of multiple bonds on the central atom
D) presence of lone pairs on the central atom
(2 points) Referring to the reading, "The Lewis Structure of Ozone," describe why the two Lewis structures shown are incorrect.
Explanation / Answer
1.
S & Se have the most similar lweis structure because of same group elements
2.
The one Mg will have a positive two charge and no dots around its symbol, whereas the two Cl symbols will have a negative charge and eight dots around the symbol.
3.
Nitrogen form triple bond with carbon and it has one lone pair.
4.
molecular geometry and electron geometry will be same if "no lone pairs on the central atom"
