Mark all the criteria that compounds must meet in order to be considered aromatic. More than one criterion must be marked
• The structure must be cyclic.
• The compound must possess a pleasant odor (aroma).
• Each atom in the ring must have an unhybridized p orbital.
• The structure must be planar or nearly planar so that overlap of these p orbitals is effective.
• The structure CANNOT contain heteroatoms (that is any atoms other than C and H).
• The π network must contain 4n + 2 electrons (where n is a whole number), thus that delocalization of the π electrons results in a lowering of the molecule's electronic energy.
Hydrazine is a toxic substance that can form when household ammonia is mixed with bleach such as Clorox. Its formula is N2H4, as well as it is a weak base. State a chemical equation showing its reaction with water. Utilize minimal integer numbers to balance the reaction.
Draw the condensation reaction that would form the dipeptide Met-Ile from the amino acids Methionine and Isoleucine. Based on the characteristics of the side chains ONLY, would you expect this dipeptide to be polar or nonpolar? hydrophobic or hyrd..
in a strongly acidic solution the amino acid lysine esists as the dication. as the pH is raised, what monocation is formed by the loss of a proton form the dication?
How much sodium nitrate (NaNO3), in grams, should be added to water to prepare .05L of solution with a molarity of .25M?
Experimentally the rate law is determined to be third order. under what conditions (if any) does your derived rate law agree with the experimental rate law
Explain most natural bodies of water have a ph range of 6-9. Explain what species are the dominant contributors to alkalinity. Utilize a speciation diagram and one or more PKa values to explain.
What would the solubility of copper (II) tartrate be in a solution that contains 0.12 M sodium tartrate?
calculate the percent yield based upon the amount of maleic anhydride used. use the molecular weight of one repeating monomer unit for the weight of the product.
You have a solution of NaCl dissolved in water. Describle a method by which these two compounds could be separated.
Calculate how many kilojoules of energy are released when 27.86g of butane are burned.
In ESI, it is very important to regulate the pH of the solution. Therefore, the solution is usually buffered or has added acid. How does the solution pH influence the ionization efficiency and the distribution of charged species formed?
Compare the polarity of hexane, dichloromethane, ethyl acetate, acetone, and methanol for tlc (thin layer chromatography)
Given the following balanced chemical equation, how many mol of NaN3 can be formed if 2.50 mol of Na are allowed to react with 4.50 mol of N2? 2Na +3N2 --> 2NaN3
