2.2 Nitromethane (CH3NO2, pka = 10) is more acidic than most organic acids. Explain why nitromethane is so much more acidic than ethane (pka = 60). Write the chemical equations to illustrate the acidity of the compounds. Include valid Lewis dot structures (including formal charge) and resonance structures, if relevant. (6)

Explain why cyclopentadiene (pKa 16) is many orders of
magnitude more acidic than cyclopentane (pKa > 50). (Hint: Draw
the structural formula for the anion formed by removing one of the
protons on the −CH2− group, and then apply the Hückel criteria for
aromaticity.)

I need question 5 answered
4. The pk, of our product is- 2-3 units lower than the pK, of phenol. Two of seven resonance forms are shown. There are five additional resonance forms that are not shown. Those additional forms have the negative charge on a different atom than the one shown on the structures below. On one of resonance contributors shown, circle the other five atoms in the structure that will have a partial negative charge as a result...

1. What is a structure based explanation for why acetamide is
more stable than acetone. I'm pretty sure it has to do with
resonance.
2. also for question F im fairly sure it has to do with
resonance again but I not sure exactly why. could someone answer
and explain?

Writing Lewis Structures d. Because oxygen is more electronegative than nitrogen, it is more likely to have a negative formal charge. Which structure would then be the best description of N,O? e. Are the structures that have the N-O-N bond skeleton resonance forms of the structures with the N-N-O skeleton? Explain. 4. Hydrogen isocyanide, HNC, will convert to hydrogen cyanide, HCN, over time. Use their Lewis structures to explain this.
