Question 2 1 pts Assign E or Z configuration to the following molecule: OOH СЕ
PROBLEM 7 13 Assign E or Z configuration to the following alkenes: (a) H3C CH2OH (b) C CH2CH3 CH3CH2 C снзо сњењенз (c) CH3 (d) H CN CO2H с с H3C CH2NH2 CH2OH PROBLEM 7-14 Assign stereochemistry (E or Z) to the double bond in the following com pound, and convert the drawing into a skeletal structure (red O);
Both (E)- and (Z)-2-chlorobutenedioic acid dehydrochlorinate to give acetylene dicarboxylic acid. The Z acid reacts about 50 times faster than the E acid. Explain. (Side note - Please explain it while explaining why syn elimination is more favorable than trans elimination. Just fill me in with some basic knowledge I need to know to answer this question, for example, anti periplanar conformations.)

2. what is the configuration of almost all naturally occurring amino acids at the a (alpha) carbon 3. why is an alpha amino acid such as alanine more acidic than a regular carboxyllic acid 4. strecker synthesis Formation dl-phenylalanine 5. outline the steps to synthesize the simple dipeptide AL (think about two amino acids that begin with an A and an L) 6. give the structure and name of the nucleosides in dna and rna 7. give the structure of...
Problem 7.7 Determine the configuration of each of the following as Zor E as appropriate: LOH Y OH (a) (b) (c) (d) Sample Solution (a) One of the doubly bonded carbons bears a methyl group and a hydrogen. According to the Cahn-Ingold-Prelog sequence rules, methyl outranks hydrogen. The other carbon atom of the double bond bears a methyl and a —CH OH group. The-CH2OH group is of higher priority than methyl. Higher (C) — Hzc CH2OH - Higher C(O,H,H) Lower...
