A) aldol condensation
B) Tischenko reaction
C) Cannizaro reaction
D) Reimer Tiemann reaction
Correct Answer: C
Solution :
Key Idea: Define all reactions to find correct answer. (i) Aldol condensation: carbonyl compound which have\[\alpha -H\]atom\[+\]\[NaOH\]\[\xrightarrow{{}}\beta -\]hydroxy carbonyl compound (ii) Reimer Tiemann reaction: \[Phenol+CC{{l}_{4}}+NaOH\xrightarrow[{}]{{}}Salicylic\,\,acid\] (iii) Cannizaro reaction: \[\underset{\begin{smallmatrix} which\,\,do\,\,not \\ have\,\,\alpha -H\,\,atom \end{smallmatrix}}{\mathop{Aldehydes}}\,+NaOH\xrightarrow{{}}alcohol+acid\] \[e.g.,\] \[2\underset{formaldehyde}{\mathop{HCHO}}\,\xrightarrow{50%\,\,NaOH}\] \[\underset{methanal}{\mathop{C{{H}_{3}}OH}}\,+\underset{sodium\,\,formate}{\mathop{HCOONa}}\,\]
