A) Fittig reaction
B) Wurtz Fittig reaction
C) Wurtz reaction
D) Cannizaros reaction
Correct Answer: D
Solution :
Key Idea: Explain all term to find correct answer [a] Fittig reaction: Two molecules of aryl halide react to form diphenyl. \[-2NaX\] [b] Wurtz Fitting reaction: One molecule of alkyl halide and one molecule of aryl halide combine in presence of sodium to form higher homologue of benzene. \[+\,2NaX\] [c] Wurtz reaction: Two molecules of alkyl halide react together to form alkane having double number of carbon atoms as in alkyl halide. \[\underset{alkyl\text{ }halide}{\mathop{R-X}}\,\,\,+2Na+X-R\xrightarrow{{}}\underset{alkane}{\mathop{R-R}}\,\,\,+2NaX\] [d] Cannizaro reaction: Aldehydes which do not have \[\alpha \]-hydrogen atom undergo disproportion reaction (half of the molecule are oxidised and half are reduced.) \[\therefore \] Benzaldehyde is converted into benzyl alcohol by Cannizaro reaction.You need to login to perform this action.
