1.	For which of the following reaction is aluminium isopropoxide a specific reagent
Answer» `R-NO_(2) rarr R-NOH` `RCOOR rarr RCH_(2)OH` `RCH=CHCHO rarr RCH=CH-CH_(2)OH` `RCH=CH-CH_(2)CL rarr RCH=CHCH_(3)` Solution :It is a SPECIFIC reagent for the reduction of carbonyl group. Thus aluminium ISOPROPOXIDE may be used for reducing aldehydes and ketones containingsome other reducible group such as a double bond or a NITRO group. [Meerwin-Pondorf-Verley (MPV) reduction].
