Which extraction procedure will completely separate an amide from the byproduct of the reaction between an amine and excess carboxylic acid anhydride?
a. add 0.1 m naoh to quench unreacted anhydride. then add diethyl ether and separate the layers. the amide can be obtained from the ether layer by evaporating the solvent.
b. add 0.1m hal to quench unreacted anhydride. then add diethyl ether and separate the layers. the amide can be obtained from the ether layer by evaporating the solvent.
c. add 0.1m naoh to quench unreacted anhydride. then add diethyl ether and separate the layers. the amide can be obtained from the aqueous layer by neutralizing with hcl.
d. add 0.1m hal to quench unreacted anhydride. then add diethyl ether and separate the layers. the amide can be obtained from the aqueous layer by neutralizing with naoh.

Someone offer some answers to this, i will give 98 coins and mark as brainliest! i will put the rest of the lab down in the comments, solutions pre-lab questions: in this lab, you will make fruit drinks with powdered drink mix. complete the pre-lab questions to get the values you need for your drink solutions. calculate the molar mass of powered fruit drink mix, made from sucrose (c12h22o11).using stoichiometry, determine the mass of powdered drink mix needed to make a 1.0 m solution of 100 ml. (hint: use molarity = to find the moles of drink mix, then convert moles to grams using a mole conversion.)what mass of powdered drink mix is needed to make a 0.5 m solution of 100 ml?
