Questions 12-20 are true and false! (12) Hydrolysis of nitriles is a method to synthesize carboxylic acid. (13) The order of reactivity of carboxylic acid derivatives is as follow: Acyl chloride > Acid anhydride > Ester > Amide. (14) SOCI2, PC13 and PCls are three types of special reagents to convert carboxylic acid to acyl chloride (15) Acyl chlorides are the most reactive common acyl derivatives, and can be used to synthesize anhydride, ester, and amide. (16) Acyl chloride is...

Rank the following carboxylic acid derivatives in order from LEAST reactive to MOST reactive when they undergo nucleophilic acyl substitution reactions: — '— ' la do lan loons obe OCH3 b. Justify your answer thoroughly in words. Your explanation should include, if applicable, definitions and explanations that cover leaving group ability, conjugate acid strengths, pKa values, etc. 4. Amide Formation Mechanism: Draw the...
I know the reactivity of carboxylic acid is acid halide > anhydride> ester > amide. "Recall that benzoyl chloride was slow to react with water, does this fit with the trend you just described? Why or why not?" So I think the answer to this statement should be it doesn't fit the trend. But could someone explain why?
