Draw the Lewis structure of acetone, (CH3)2CO(CH3)2CO.

In complete sentences, describe why someone might expect the bond angles in methane (CH4) to be 90°, although the bonds are actually 109.5°.

Consider a Lewis structure of acetamide H3C-C(O)-NH2 . How many bonds to other atoms oxygen atom has in the above molecule?   How many shared and unshared electrons carbon atom attached to three hydrogen atoms has in the above molecule?   How many shared and unshared electrons nitrogen atom has in the above molecule?   How many shared and unshared electrons carbon atom attached to oxygen has in the above molecule?   How many shared and unshared electrons hydrogen atom has in the above molecule?

An incomplete Lewis structure is shown below. The structure only shows the atoms and how they are connected. The molecule has a net charge of zero. H Н—N—С- -о—с—Н H H Complete the Lewis structure giving all atoms full octets. If there is more than one way to do this, draw resonance structures showing all possibilities. If not, just draw one Lewis structure. Be sure to write in any non-zero formal charges. Click and drag to start drawing a structure.

10. Molecule: CzHj0 Indicate the number of available electrons that are in the molecule. ae = Trial Structure: in the space to the right connect all of the atoms to the central atoms (all Cs in a chain) and then make each atom follow the octet rule (duet rule for hydrogen). How many electrons are necessary in the trial structure? ne = Circle the correct ne = ae ne ae relationship between ne and ae. Draw the corrected Lewis Structure to the right. Add Later: e- geometry: molecular geom: Hybridization:

Can you help me with the Ni3 step-by-step for number (Step 6)? I need help with the central atom surrounded by an identical electron group. I need help with the molecule polar.

♥ Draw Lewis structures for each of the following. Use the DEN and the number of REDs around thecentral atom to select the type of bonds, the molecular shape, and type of molecule from the lists.♥ Do not put covalent bonds between metals and nonmetals♥ Put brackets around anions to show both charge and quantity.

H-0-F: Draw the correct Lewis structure for HOF, including all lone pairs of electrons.

Р ed Lewis structure H-CC-H [H_H_O_H]* Η N_0_a: Is the proposed Lewis structure reasonable? Yes. No, it has the wrong number of valence electrons. The correct number is: No, it has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are:* Yes. No, it has the wrong number of valence electrons. The correct number is: No, it has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are:* Yes. No, it has the wrong number of valence electrons. The correct number is: No, it has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are:*

What is wrong with this Lewis dot structure for the H₂CO molecule? :Ö: 0- I H-C-H
