Which nucleophile will readily react with the following compound to produce an. more stable product?Explanation / Answer
Question 20: The best reagent is DIBAL-H, -700C
Explanation: DIBAL-H is a selective reducing agent which reduces acid chloride to aldehyde.
Question 19: All of the above (a-d) will react to produce a more energetically stable product.
Explanation: Reaction of acid bromide with Cl- produces acid chloride, reaction of acid bromide with carboxylic acid produces anhydride as product. reaction of acid bromide with carboxylic acid produces ester as product.
Question 18: Nucloephilic addition is not required in this reaction.
The base abstracts a proton and produces a negative charge on nitrogen atom which on further reaction with alkyl halide produces SN2 reaction.
