Question

Name: Consider the following compound: a. (4 pts) Write its systematic name: b. (2 pts) How many equivalents of a Grignard reagent would react with it 2. (3 pts) Consider the following compound: a. (3 pts) In the space above, write the names of all the carbonyl-containing functional groups in it. b. (2 pts) On the structure, circle the two carbonyls that are the most electrophilic (no need to decide which is most vs second-most). Consider the following reaction, whose product contains at least one carbon-nitrogen bond: H, H2O (3 pts) In the space above, draw the final major organic product(s). b. (2 pts) What effect (if any) does the cyclopropyl group have on the rate of this reaction? Explain in one sentence.

Answer 1

Answer 1)

Hm... 4CH, O H mm..... (8) CH3 3 (S)-n-propyl 3-methylpentanoate a) Ester is considered as the derivative of carboxylic acid and hence names ac cordingly. a longest chain of C containing carbonyl carbon is selected as parent and as its a carboxylate equivalent part is name accordigly. Here it is of 5 C hence end as ....pentanoate. b) C: bears -CH3 methyl substituent c) alkoxy equivalent part is n-propyl as placed at the begining. d) C3 is stereocentre and stereodescriptor is determined using Cahn-Ingold-Prelog rule. Hence the name shown. 2) Esters generally takes 2 moles of Grignard reagent to reduce completely to alcohol(s) General reaction i RMX ROMgX RO + XMg-OR1 * R REOR, Mole 7 R OR, R2 SORI R Mole 1 XMg RMgX oMgx но to RETR R2R OH XMg-OR1 unreacted RO-OH unreacted
