a molecule is made from 4 atoms. the first atom (A) has 5 valence electrons, the second atom (B) has 1 valence electron, and the other two atoms (C) each have 7 valence electrons. what is the shape of the molecule ABC2?

Use this condensed chemical structure to complete the table below. Br Br The condensed chemical structure of para-dibromobenzene. Some facts about the para-dibromobenzene molecule: molecular formula: number of major resonance structures: number of carbon-hydrogen single (C-H) bonds: number of lone pairs: 0 X Ś

The compound below (Cl2O2) plays a role in ozone depletion in the stratosphere, where it serves as a reservoir of Cl atoms that catalyze the destruction of O3. Draw a Lewis structure for Cl2O2 based on the arrangement of atoms shown above.

When drawing the Lewis structure of the HCC13 molecule, the structure should represent a total of 26 valence electrons. What is the best description of the complete Lewis structure of the molecule? Select one: AH atom should be in the center with single bonds to each Cl atom and a double bond to the C atom. A Cl atom should be in the center with a single bond to the C atom and a single bond to the H atom. AC atom should be in the center with a double bond to the H atom and double bonds to each Cl atom. AC atom should be in the center with single bonds to each Cl atom and a single bond to the H atom.

Some formulas can be drawn multiple ways; molecules that share the same formula but have different structure are called isomers. Draw three isomers with the formula C5H12O such that each atom makes the appropriate number of bonds, as indicated by their Lewis Dot Symbol. (There are many structures that work!)

Decide whether these proposed Lewis structures are reasonable. proposed Lewis structure :Z: I :Z: c=0 0 0 0 Is the proposed Lewis structure reasonable? O Yes. O No, it has the wrong number of valence electrons. The correct number is: O O 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:* O Yes. O 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:* * 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 3

how would i approach this

None

C5H12  What is the electron geometry around each C? Does the geometry around any of the carbon atoms change from structure to structure? Does the overall shape of the molecule change? Describe these changes.
