6. Usina resonance structures, explain why acetaldenyde has a pka of 17, while acetone of 19. 7. Using resonance st...
Explain why the different positions have different pKa values,
using resonance structures.
The pka of phenol (C6H5OH) is 10.0. When a nitro group (NO) is attached to the ring, the pka decreases. Explain why the different positions have different pka values, using resonance structures. OH OH OH - ၄ NO, NO₂ 10. 0 pK, = 7 .23 8.35 7.1
Explain why compound A is more acidic using resonance structures
and question 21.
WILLUDUlyalli Clemsty ENAM 20. Explain why Compound A is more acidic than Compound B. Use resonance structures to e 21. Which of the following is the least stable carbocation? Circle your response. (2) IV
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)
5. a) which proton in A is most acidic? Explain thoroughly with resonance structures. b) Decide whether A is more or less acidic than B, and explain your choice.
Using resonance structures and a brief explanation, explain why phenol (C6H5OH) is an ortho-para director (25 pts).
Complete for a thumbs up! a. Explain resonance. Use images to help defend your explanation. b. Create a table listing the trends on the periodic table of increasing atomic radius, electronegativity, and polarity. c. Rank these compounds in order of least polar to most polar: CH4, H2O, HCl, and NO2. d. Draw the Lewis dot structures for CH4, H2O, HCl, and NO2.
Using resonance structures as part of your answer, explain why Br in bromobenzene is: a. A mild ring deactivator b. An o-, p-director. [Note: It is not enough to use resonance structures from part "a" to "prove" part "b". One must show that o-, p-attack is faster, i.e. has lower Ea (AGa) by actually showing an electrophile, e.g. the generalized E+, attacking at the o-, m-& p-positions and, using Hammond's Principle, explain why the o-, p-attacks are favored.] Explain what...
3) Draw resonance diagrams to explain why phenol has a pka pf 10 whereas aliphatic alcohols like ethanol have a pka of 16. 4) Why are aldehydes generally more reactive towards nucleophilic attack than ketones? 5) Suggest possible steps involved in the synthesis of the following compound starting propene. Note for each step involved your desired product must be a major product. Also note the two arrows indicate an unknown number of steps are involved.
Question 12 6 pts Explain using drawings why acetaldehyde reacts faster than acetone to nucleophilic acyl addition. Include your answer sheet upload to Canvas in the Assignments folder or email your answer to Dr. Berger. Note: there may be more than one way to answer this question. Only one correct explanation is required. For partial credit draw acetaldehyde and acetone
Can you please explain these throughly!! I will give good rate
thank you!!
