Draw a Lewis structure for the compound whose skeletal structure is provided to you below. Don't forget to draw in the H atoms! CH₂ HC CH 11 HC — CH, - Draw the Lewis structure by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons.

Decide whether these proposed Lewis structures are reasonable. proposed Lewis structure :C=0: [H_H_O_H]* :F=0=F: Is the proposed Lewis structure reasonable? Yes. No, it has the wrong number of valence electrons. The correct number is: 0 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:0 No, It has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are: 0 O 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:* 0 If two or more atoms of the same element don't satisfy the octet rule, just enter the chemical symbol as many times as necessary. For example, if two oxygen atoms don't satisfy the octet rule, enter "0,0". X Ś

Use the table of electronegativities in your notes (textbook) to answer this question. Which of these bonds involving carbon is the MOST polar? Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a C-O b C-CI C-F d. С-Н e C-N

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.

Designate the structural features of polar molecules using partial charges or arrows. Ethyl heptanoate is responsible for grape aroma. It has the chemical formula C9H1802 but structural formula CH3-(CH2)s-COO-CH2-CH3. A structure is shown below. Which bonds would feature partial charges? Designate them using partial charges or arrows. H H H | H H H H

Can u help me with this qu

Write a Lewis structure for each of the following molecules. H3COCH3 (oxygen is between the two carbon atoms)         Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons.

For the formula CH2CF2, "draw the Lewis structure in your work After drawing the complete Lewis structure, type in the shape, bond angle, etc. for each blank. What is the molecular shape or geometry for the carbon on the left (the C in CH2)? What is the molecular shape or geometry for the carbon on the right (the C in CF2)? What is the bond angle for the carbon on the left (the C in CH2)? Type in a plain number, but include a "<" sign in front of the number if applicable. What is the bond angle for the carbon on the right (the C in CF2)? Type in a plain number, but include a "<" sign in front of the number if applicable. What is the hybridization for the carbon on the left (the C in CH2)? Type this in without any superscript, for instance sp3 would be typed as "sp3". What is the hybridization for the carbon on the right (the C in CF2)? Type this in without any superscript, for instance sp would be typed as "sp3". Is the molecule overall polar or nonpolar? Simply type "polar" or…
