Concept explainers
Interpretation: The resonance structure of the adenine molecule which is part of the DNA should be drawn.
Concept Introduction: Sometimes the
All the possible resonance structures are imaginary whereas the resonance hybrid is real. Any of the possible structure does not exist as such like a stable real molecule. So it is not possible to isolate one resonance structure.
While drawing resonance structure of a molecule some rules should be followed where the position, over whole charge and chemical framework remains intact. Also only π and nonbonding electron has been moved in all the three resonance structures.

- Answer the questions in the table below about the shape of the phosgene (COCI,) molecule. How many electron groups are around the central carbon atom? Note: one "electron group" means one lone pair, one single bond, one double bond, or one triple bond. What phrase best describes the arrangement of these electron groups around the central carbon atom? (You may need to use the scrollbar to see all the choices.) (choose one)arrow_forwardComplete the following statements about the molecule COS. Please note that ALL atoms in this molecule obey the octet rule. The molecule COS has total valence electrons. The molecule COS should be drawn with C in the middle, O to the left of the C, and S to the right of the C. After drawing the Lewis structure for COS using the above information, it is evident that the three-dimensional shape (or geometry) of the molecule is , with a bond angle of degrees.arrow_forwardPlease don't provide handwriting solutionarrow_forward
- Draw a Lewis structure of your choice that has at least three equally reasonable resonance structures. You must show your work as to how the structure was drawn including showing valence electrons, any structures you draw that don’t work and require you to show a multiple bond, and formal charges on each atom that has a formal charge. For example, Nitrate ion has three structures (but you can’t draw this one). All three structures have formal charges and no one structure is preferred based on formal charge. Carbon dioxide would not be a valid choice. While it does have three structures, the structure that has two double bonds is the preferred structure while the structures with triple bonds are not equivalent to the double bonded version as they have multiple formal charges present.arrow_forwardFollowing is a molecule with polar bonds whose shape was obtained using the VSEPR theory. Specify the molecular shape of this molecule, and whether the molecule is polar or nonpolar. (Hint: In terms of polarity, see whether the dipoles in the molecule cancel or not. A molecule containing polar bonds can be nanpolar if the dipoles cancel each other. You can imagine the dipoles as ropes pulling on the central atom–If the pulls cancel each other, that is, the central atom cannot move, then the molecule is nonpolar. If on the other hand the opposite is true, then the molecule is polar.)

Which of the follow statements is false? This notation represents a blend of two equivalent resonance structures. O Each vertex of the hexagon represents a carbon atom, and the hydrogen atoms have been omitted. O The circle indicates that there are three double bonds in each individual resonance structure for the molecule. O This notation is used because there are no Lewis structures for benzene that satisfy the octet rule. Submit Request Answerarrow_forward
