Directions : In the following question more than one of the answers given may be correct. Select the correct answer and mark it according to the code:
Which compounds give Cannizaro's reaction? (1)\[HCHO\] (2) \[{{C}_{6}}{{H}_{5}}CHO\] (3)\[C{{H}_{3}}C{{H}_{2}}CHO\] (4) \[C{{H}_{3}}COC{{H}_{3}}\]A) 1, 2 and 3 are correct
B) 1 and 2 are correct
C) 2 and 4 are correct
D) 1 and 3 are correct
Correct Answer: B
Solution :
In Cannizaro's reaction aldehyde which do not contain any a-hydrogen atom undergo self oxidation and reduction reaction on treatment with concentrated, solution of caustic alkali. HCHO and\[{{C}_{6}}{{H}_{5}}CHO\]give Cannizaro's reaction because they do not consist a-hydrogen atom.
