Concept explainers
Interpretation: The illegal arrows in below set of arrows should be determined.
Concept introduction: Lewis structure is a representation of molecules in which dots are shown to represent unshared electrons and lines are shown to represent bonds. These lines and dots represent distribution of electrons in the molecule.
When one single structure is unable to describe all the properties of a single-molecule, a phenomenon called resonance comes into play. This arises when two or more than two Lewis structures are possible for one molecule. All such structures are called resonating structures and have same placement of atoms in them but these have different locations of bond pairs and lone pairs. The resonating structures are inter-convertible with each other. The resultant of all the resonating or contributing structures is called the resonance hybrid.
Rules to form resonance structure are as follows:
1. Use arrow types 1 and 2 for the resonance structure of anions in the movement of negative charge.
2. Use only arrow type 3 to move a positive charge for the resonance structure of cations.
3. The sigma bond should not be broken. Any atom must not move from its place and total number of electrons must be the same in all resonance structures.

- Please don't provide handwritten solution.....arrow_forwardBenzene is especially stable due to... O the electrons of the double bonds are delocalized O its planar shape the total number of carbors in the molecule each carbon has four bonds « Previousarrow_forwardCould we cut just one bond in the "starting" molecule shown in the drawing area below to create this "target" molecule? The target molecule. If so, highlight the bond to be cut. If not, check the box under the drawing area that says Not possible. Note: it's OK if cutting the bond creates more than one molecule, as long as one of them is the target molecule. ? O Not possible. Note for advanced students: what we mean by "cutting" the bond here is breaking the bond and attaching H atoms to each dangling end, like this: H. H. Н—с—ӧ—н Н—с—Н H-ö-Harrow_forward
- Draw two significant resonance structures for the molecule below (start at the same site of instability for both). Only one lone pair and formal charge are provided; provide any formal charges and lone pairs that are missing on the original structure and on your resonance forms. Make sure to draw curved arrows correctly (starting from a bond/lone pair) and be very clear where the head of the arrow is pointing. Finally, rank them from most stable to least stable and justify your choices. The skeleton for your resonance is provided.arrow_forwardGive a clear handwritten answer with explanation..give answer all sub partsarrow_forwardI only need part D!!! Thank you.arrow_forward
- 3) Enols are an important class of molecules in organic chemistry, which are utilized for theirability to form carbon-carbon bonds. We will learn about their unique reactivity much later inthe course. Shown below is an enol on the left, whereas the molecule on the right is classifiedas an allylic alcohol. a) Please explain why the structure on the right IS NOT a resonance structure of the enol on theleft. A short statement or illustration is fine, be sure that your rationale is clear. b) Draw the correct resonance structure that can be produced from the enol on the left. Besure to include arrows to indicate the movement of electrons in the left-hand structure andindicate charges in the resulting structure. c) What is the hybridization of the carbon indicated with the red arrow?arrow_forwardorganic chemistry Diels Alder..

Draw each SALC that you generate and each orbital within the final MO diagram. Label your orbitals as o", n, o' etc. and include the appropriate # of electrons. Compare your MO diagram to the Ta version done in class and provide an explanation for which geometry you think is would be more stable. Hint: you can use the d-orbitals as a template though they are not available for bonding.arrow_forward
