Indicate the reaction conditions you would employ to accomplish the following: a. Conversion of tert-butyl chloride to 2-methylpropene to maximize the yield of the elimination product over the substitution product. b. The conversion of tert-butylchloride to tert-butyl ethyl ether to insure the highest possible yield of the eth

Please see attached structures and name them (I'm new to drawing in Word. Get ready for a good laugh.)
Please see attached for diagram ... Questions: Will this disaccharide give a positive Benedict's test? Why or why not? Does this structure have a hemiacetal, hemiketal, acetal, or ketal system? Locate it on the drawing & give appropriate label. Upon hydrolysis with the appropriate enzyme, what will be the products?
Complete the reactions. 1. What does stearic acid and sodium hydroxide yield? 2. C-C-N-H +HCl H 3. H2 CH3CH2(CH=CHCH2)5COOH Pt 4. O = C-O-C-(CH2)12CH3 - 5. O =
Hi. We were given a practice sheet with review questions. Can you briefly tell me why on each so I can apply it on test? Thanks. Higher solubility - Butanedioic acid or Butanal Higher mp - 2,3-dihydroxy propanal or Pentanal Lower mp - Sodium octanoate or Octanoic acid Lower solubility - 2-hexanone or 2-hexanol
Why sugar burns rapidly with ignited but shows no reaction under normal conditions (ie a sugar bowl)
Why is sugar stable under standard conditions. In contrast to the high stability of sugar in daily use it burns rapidly when ignited without any 'booster' like sulphur or alkali nitrates.
What determines whether a group on a benzene ring will be activating or deactivating and ortho para or meta directing?
How can you know that HNO3 is nitric acid and HNO2 is nitrous acid? How do you know the difference in endings? Is there a formula for this to tell the difference? They are so closely related. I see this is common when naming acids. How can you tell as well, that HCLO is chloric acid. I would think it was hydrochloric acid.
I am having some trouble explaining why the attached molecule is an otho-para director although a weak deactivator. I believe it is because of resonance forms, but that is as far as I have gotten. Thanks,
What is the hybridization of an AXmEn molecule? How can I find the AXmEn formula?
1. Draw the structure of Compound A based on its formula and proton NMR. The integration of the peaks from left to right is 5:2:1. Compound A, MF C7H8O 2. Draw the structure of Compound B. Hint: The IR spectrum shows a strong bond at 1725 cm^-1. 3. Draw the structure of Compound C. Hint: The IR spectrum shows no peaks nea
Molecule 1: 5 carbon ring, carbon 1 has a carbon attached which also is triple bonded to another carbon (this end carbon just has a H attached.) There is also a double bond between carbons 1 and 2 in the ring. Predict the product when this reacts with KMnO4 in H30+. Molecule 2: I have a 6 carbon ring. C1 has a C which is
For problems 1 through 3, determine the functional group from the following spectra. There is only one functional group per compound. Determine whether the compound is aromatic or not aromatic. Follow the instructions attached.
Explain the following: a.) The cycloheptatrienyl anion is antiaromatic, whereas the cyclononatetraenyl anion is planar (in spite of the angle stain involved) and appears to be aromatic. b.) Although  annulene is not aromatic, it adds two electrons readily to form an aromatic dianion.
Provide a retrosynthetic analysis and the forward synthsis of the following molecule, starting from commercially available compounds. The retrosynthesis should clearly identify the synthons and their synthetic equivalents. Functional group interconversions and bond disconnections should be clearly indicated where appropriate. Th
Show the mechanism and product of the following electrophilic addition to a conjugated diene using curved arrows to show bond-making and bond-breaking process. (See attachement for full question)
Provide me with your exact logic used to get the answer. A mysterious material was purified from safflower oil (hint: full of fatty acids). Upon ozonolysis it gave the following compounds in their respective molar ratios. Draw the structure of the mysterious material and give me its common name. 3 moles CHOCH2CHO 1 mol
I am trying to synthesize 3-hexanone from acetylene and ethyl bromide. Any help with how this can be done?
I need help determining how the products below might be formed and what their structures might look like: Br2(over Arrow) 2-butyne --------->C4H6Br2(28%yld) + C6H12Br2O2(65%yld) CH3OH(under arrow) Thanks for any help!
I need some help to get me started: Determine the weight in grams of sodium dihydrogen phosphate (M.W.138.01) and disodium hydrogen phosphate (M.W 141.98) needed to prepare 1L of a standard buffer at pH 7.00, with a total phosphate concentration of 0.100M. Okay I know that the pKa is going to be 6.86. I am therefore going
I am pretty sure that I have figured out the problem, just one peice is stumping me. Do you think that you can help me figure out the structure and name. What I have may possibly be right. Question: Analyze the data given in each of the problems below, deduce the structure and give the name. A fishy-smelling liquid with

Lidocaine is thought to bind to receptors in its methylated form. identify in writting the atoms or groups in the compound that could be involved in its binding to a receptor via- hydrogen bonding (1 example) an ionic interaction give the 2 types of functional groups that need to be present in the receptor s
Draw the abbreviated structural formula of the products of the complete hydrolysis of lidocain. Identify any new functional groups naming them clearly.
My questions are: what would the question look like for which this NMR can be used? What would the IR and mass spectrum look like? What do I need to recognize on each spectrum to answer the same questions given in the Garden Cress problem?
