Briefly explain the two reasons why the radical anion on the RIGHT is more stable than...
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.) Explain why cyclopentadiene (PK, 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,...
There are more cells than organelles in the human body. Briefly explain why it is false or reword it to make it true.
why are benzene rings more stable than alkenes? use diagrams to explain your answer
Could anyone explain why the first compound is more stable than the one I circled? And also, why is resonance a stronger influence and not induction? Thanks! 15. Circle one of the following charged compounds which is most stable. (3 Points) Which is the stronger influence for your choice? a) Resonance or b) Induction (hyperconjugation)? (2 Points)
Why is ion A more stable than ion B? 5. (a) Why is ion A is more stable than ion B? (b) What would you look up to quantitatively estimate the energy difference between them?
xplain why chelating ligands give more stable complexes than monodentate ligands; use a balanced chemical equation in your explanation. Explain why macrocyclic ligands give more stable complexes than chelating ligands.
for question 19 can you explain why you picked the reagents you did? Sterist CH; HC CHH; CCH; - CC CH trans vinylic anion more stable anion able cis vinylic a less stab electron repulsion cis radical anion less stable Hical anion is more stable than the cis radical anion, because the nonbonded electrons are farther apart i The trans vinylic anion is more stable than the cis vinylic anion, because the relatively bulky alkyl group in the trans isomer...
c) Briefly discuss ONE method of manufacturing a metal matrix composite and give TWO reasons why it is more difficult to manufacture ceramic matrix composites. (8,4)
Tell briefly one or two of the differences between the radical behaviorists (Watson; Skinner) and the cognitive-behaviorists (methodological behaviorists, like Hull, Bandura, Tolman, and Rotter). If you could work as a student intern with one of them, who would it be and why? (There is no right or wrong answer.) Write 3-12 sentences total.
a) What are the two major reasons why III-V materials are more difficult to process than silicon? b) What is the liquid that is used as the solvent in liquid phase epitaxy of III-V materials?
