The following two drawings are resonance structures of one compound. a-o But the following two drawings are not resonance structures Not resonance structures They are, in fact, two different compounds. Choose the correct explanation(s). Select all that apply. Benzene does not have three C-C single bond and three C-C double bonds. In fact, all six C-C bonds of the ring have the same bond order and same length. Benzene have three C- single bond...

H CH3 1. LDA 2. CHal НН H3C CN H3C CN Monocarbonyl compounds can be alkylated at the a position via the use of lithium disopropylamide, a strong, sterically hindered base Because only one carbonyl group is available to participate in resonance stabilization of the enolate, the a-hydrogens are less acidic than those of P-dicarbonyl compounds and so a stronger base is necessary to completely convert the compound to the enolate. The reaction occurs in a pola aprotic solvent such...

Prelab Assignment You are asked by your instructor to draw the Lewis structure of the NHCI molecule. Being of a conservative nature, you proceed as directed in the Procedure section. 1. First, find the number of valence electrons in NHECI. For counting purposes with Lewis structures, the number of valence electrons in an atom of a main group clement is equal to the last digit in the group number of that element in the Periodic Table. N is in Group...

A) You need to do ONE thing in this MarvinJS editor. Draw the
electron flow arrows showing the step where the benzene derivative
participates in the reaction that leads to the final major organic
product. B) Draw the skeletal structure of the major organic
product. The deuterium isotope (D) must be shown explicitly. C)
Draw ALL the resonance structures needed to depict the arenium ion
for this reaction. Include all lone pairs of valence electrons and
all D's.

Pre-Lab Exercise 2-3 Chemical Bonding One of the more challenging concepts to grasp in chemistry is chemical bonding, a topic that pops up again and again in A&P: We revisit it in cytology, the nervous system, blood, respiration, and digestion-to name just a few First let's do some basics. Use your textbook and this unit to answer the following questions 1. Do metals donate or accept electrons? What do they become after they donate/accept electrons? 2. Do nonmetals donate or...
