The approximate Lewis structure of CH2O is this:

H

\

C==O

/

H

It is the most basic aldehyde, often referred to as formaldehyde. The bond lengths are:

C-H bond: 1.113 Angstroms

C=O bond: 1.208 Angstroms

The measured bond angles are:

HCH: 117.46 degrees

HCO: 121.27 degrees

The Lewis dot diagram for C2H3OH would show the carbon atoms bonded together in the center, each with a single bond to one of the hydrogen atoms, and one carbon forming a double bond with the oxygen atom. The oxygen atom would have two lone pairs of electrons.

Previous Answer: i need this too!

New Answer:

Total electrons: 8 (C) + 3 (H) + 6 (O) + 1 (H) = 18

______H

______|_____..

___H - C - C = O

______|__|___..

______H_H

Try to ignore the horizontal lines. I used them to keep the format of the structure.

It won't keep my format, but basically, you have the first Carbon bonded with 3 Hydrogen atoms (top, left, and bottom). The Carbon is bonded with the second Carbon (right) which is then double bonded to the Oxygen (which has two lone pairs, top and bottom). The second Carbon is attached to a hydrogen atom (below it), also.

That would be the best bet, I think. I did a lot of similar structures in my homework, but not this one specifically. I hope it's right, and I ! :)

h-c=o |
o-h


It's hard to show...but Carbon is your central atom....it is double bonded with one oxygen, single bonded with the other, and single bonded to one Hydrogen, the remaining Hydrogen is single bonded to the oxgen, that is single bonded to the carbon.


All in all, Carbon should have no more than 4 bonds, Oxygen no more than 2, and Hydrogen can only have one.

What is the electron dot diagram for xenon?

The electron dot diagram for xenon would show the symbol Xe surrounded by eight dots, representing the eight valence electrons xenon has in its outer shell. This configuration allows xenon to fulfill the octet rule and be stable.


What includes the symbol for an element surrounded by dots?

The symbol for an element surrounded by dots typically represents an atom with the nucleus at the center (symbol) and electrons represented by dots surrounding it to show their arrangement in energy levels. This depiction is used to illustrate the electron configuration and distribution of electrons in the atom.


What is the electron dot diagram for lead?

The electron dot diagram for lead would show the symbol for lead (Pb) with four dots around it. Two on the top side and two on the bottom side, representing the four valence electrons in the outer shell of a lead atom.


How many electron must be shown for the lewi dot structure of formaldehyde?

The answer is 12. If you draw the lewis dot structure for formaldehyde, you have to remember to draw the non-bonding pairs on the oxygen atom, and when you count all the electrons, remember that the lines used to represent bonds are counted as 2.


What is the p p dot diagram of pulsar?

The p-p dot diagram, also known as the Pulsar Diagram, plots the rotation period (P) of a pulsar against its time derivative of rotation period (Pdot). It is a key tool in studying the evolution of pulsars, helping astronomers understand their age, magnetic field strength, and energy output. Pulsars typically follow a trend in the diagram known as the death line, marking the boundary below which pulsars no longer emit detectable radio pulses.
