QJEEM12Chc705: JEE Main 2012 Chemistry - Class 12 JEEM12Chc705 Solution: In the given transformation, which of the following is the most …

Aldehydes and ketones can be reduced to hydrocarbons by the action $(i)$ of amalgamated zinc and concentrated hydrochloric acid (Clemmensen reduction), or $(b)$ of hydrazine $\left( {N{H_2}N{H_2}} \right)$ and a strong base like $NaOH,KOH$ or potassium tert-butoxide in a high-boiling alcohol like ethylene glycol or triethylene glycol (Wolf-Kishner reduction )



$-OH$ group and alkene are acid - sensitive groups so clemmensen reduction can not be used. Acid sensitive substrate should be reacted in the Wolf-Kishner reduction which utilise strongly basic conditions.
