For all of the multiple choice write the letter of your choices in the provided blanks. Use the following choices for questions 1-10. OH ndo.O.O .. Which compound is an ester? Which compound will react with peroxy acids (e.g. MCPBA) to form a 7-member ring cyclic ester? Which compound is an amide? Which compound is an acetal? Which compound is not hydrolyzed (ring opened) by aqueous acid? Which compound will not react with Grignard reagents? Which compound is an anhydride? Which compound reacts with NaBH/MeOH to form an alcohol? Which compound is a hemiacetal? Which compound reacts with aqueous acid to form formaldehyde and 1,3-propanediol? Why are aldehydes more reactive than ketones toward nucleophiles? "Because aldehydes have A. less steric hindrance B. less inductive stabilization C. both A and B D. none of these Which of these does not react with cyclohexanone under mildly acidic conditions? A. Et3N B. Et2NH C. EINH2 D. they all react
