) For the two dienes shown, shade in the lobes of the four molecular orbitals (on the left) and then populate the appropriate orbitals with pi electrons. Next, in the middle diagram, shade in the lobes of the highest occupied molecular orbital that is used in part a) for thermal electrocyclization. Draw the expected product in the box and explain briefly, using terms such as conrotatory and/or disrotatory, why that particular stereoisomer is formed under thermal conditions. Repeat this process in part b) for the photolytic situation. 8888 8888 8888 a) & CH3 CH3 - - ff 28 H₂C A

Draw relevant resonance structures for the the phencyclone reactant that explains the lower absorption frequency of the C=O group in comparison to a diels alder adduct. When drawing resonance structures show appropriate arrows, and only move one pair of electrons at a time going from one to the next; show lone pairs and charges, as appropriate. Comment in a sentence or two. Do not involve the double bonds from the benzene ring...
Please clarify if the arrows are a single electron moving or a pair, thank you!
Need help solving this, please show your work with the answer!
For the addition reaction below, determine the three possible products and show the FULL electron-pushing mechanism and ALL intermediates (including lone pairs and formal charges) to depicts how each one of the three products is obtained. Don't forget to explicitly show how the hydride shift happens to obtain the major product.
Am I doing the first one right, can you show the right answer if not. For my 2nd question, can you draw the curved arrow notation clear and right, please?

2. Draw in the curved arrow mechanism and predict the major, neutral product consistent with the fact that the only interesting peak in the IR is a broad, symmetrical stretch at 3253 cm²¹. In reality, this is not the final, most stable product possible. We will discuss more in chapter 21. Assume H₂O is present in a large excess as solvent. Show all bonds formed and all bonds broken. Be sure to draw all intermediates and include formal charge where applicable. In a few words, describe the regioselectivity of the reaction. H3O+ H₂O
