Lewis Dot Structure Generator

1 Lewis Dot Structure Group Exercise – CHEM 1140

1.

Find the correct Lewis dot structure for the carbonate ion.

Include all resonance structures.carbonate

CO32

# e- = 4 + 2(6) + 2 = 24 e-

OOOOO
2.

Draw the correct Lewis dot structure for the formaldehyde molecule, CH2O.

Describe the shape of the molecule.

Is the molecule polar or nonpolar?

# e- = 4 + 2(1) + 6 = 12 e-

HH

The shape is approximately trigonal planar.

The molecule is polar.

(Top half is a little negative and the bottom half is a little positive.)

2 3.

Draw the correct Lewis dot structure for the ethanol molecule, CH3OH.

Describe the shape of the molecule.

Is the molecule polar or nonpolar?

# e- = (2)4 + 6(1)+ 6 = 20 e-
The shape is definitely not flat.

Its somewhat prism-like with a bent leg hanging off of it.
The molecule is polar.

.

Draw the correct Lewis dot structure for sulfur tetrafluoride.

Make a guess about the shape and whether it is polar or nonpolar.

sulfur tetrafluoride

SF4

# e- = 6 + 4(7) = 34 e-

FF The electron pair geometry is called trigonal bipyramidal.

The molecular geometry is called see-

The molecule is polar.FFFHHCHHHHCHH 3 5.

Draw two different Lewis dot structures corresponding to two different molecules for the chemical formula, C3.

The names of the two different molecules are propene and (if time).

Draw the Lewis dot structures for the molecules ClO2 and NO2What is the unusual characteristic of these molecules?

Compare these structures to the structures for the chlorite and nitrite ion.

For ClO2 #e = 7 + 2(6) = 19 e-
For N #e = 5 + 2(6) = 17 e-
For ClO2 #e = 7 + 2(6) + 1= 20 e-
For N #e = 5 + 2(6) + 1 8 e-
The usual characteristic about the ClO2 and NO2 molecules is that they have an odd number of electrons.

However, note that ClO2 and NO2 have an even number of electrons and satisfy the octet rule.CCHCHHHHHCCHHHHHHOOOO.

My electrons in a lewis valence electron dot structure
I am in group 2 on the periodic table so I have 2 valence electrons! This is my Lewis Dot Structure!
Lewis dot structure
so on the poster I'm suppose to put the Lewis dot structure of each element in the compound Wtf is that?!?!
I know this girl is not telling me what I should know about electron pair geometry when she can't even draw the lewis dot structure.
" Honestly I'm like f*ck a Lewis dot structure and its stupid electron geometry." U will do fine ;-)
I that I get a good grade on this chem test. And if I have to write another Lewis dot structure I might kill someone
My Lewis Dot Structure. I have one Valence Electron. In this configuration.
The latter one is a short article describing the chemistry of aspirin and it shows the lewis dot structure of it.
