Cyanide in the presence of acid 8.) Hydoxylamine 9.) Phenylhydrazine 10.) 2,4-nitrophenylhydrazine 11.) Ethanol and dry HCl 12.) Semicarbazide
1.) Tollen's Reagent 2.) CrO3/H2SO4 3.) Cold Dilute potassium/H+/Heat 4.) Lithium aluminum hydride 5.) Sodium borohydride 6.) Phenylmagnesium bromide then water 7.) Cyanide in the presence of acid 8.) Hydoxylamine 9.) Phenylhydrazine 10.) 2,4-nitrophenylhydrazine 11.) Ethanol and dry HCl 12.) Semicarbazide
Explanation / Answer
1.) Tollen's Reagent = corresponding carboxylic acid
2.) CrO3/H2SO4 = corresponding carboxylic acid
4.) Lithium aluminum hydride = alcohol
5.) Sodium borohydride = alcohol
6.) Phenylmagnesium bromide then water = alcohol with phenyl derivative.
7.) Cyanide in the presence of acid = Cyanohydrin
8.) Hydoxylamine = oxime
9.) Phenylhydrazine = Phenylhydrazone
10.) 2,4-nitrophenylhydrazine = corresponding hydrazone
12.) Semicarbazide = semicarbazone
