Vedclass · Answer

(B) In $A$,Clemmensen reduction $(Zn-Hg/HCl)$ reduces a carbonyl group $(>C=O)$ to a methylene group $(>CH_2)$. This is correctly matched.In $B$,Wolff-Kishner reduction $(NH_2NH_2/KOH, \Delta)$ reduces a carbonyl group $(>C=O)$ to a methylene group $(>CH_2)$,not an alcohol $(>CH-OH)$. Therefore,this is incorrectly matched.In $C$,Rosenmund reduction $(H_2/Pd-BaSO_4)$ reduces an acid chloride $(-COCl)$ to an aldehyde $(-CHO)$. This is correctly matched.In $D$,Stephen reduction ($SnCl_2/HCl$ followed by $H_2O$) reduces a nitrile $(-C \equiv N)$ to an aldehyde $(-CHO)$. This is correctly matched.
