hey friends
can someone please list down all the selective reducing or oxidising agents and the groups that these compounds reduce or oxidise

this would b helpful to all and i would surely b grateful of u

someone please reply

i meant in organic chem
see the forum man

umm.. i know a few..

(NH₂)S is used to selectively reduce one of the 2 (or more) nitro groups
in a benzene ring. but the nitro group it reduces depends in various factors like steric, H- bonding, etc.

then P/HI is used to reduce a -COOH grp to -CH3 tho im not sure if its selective in natture or not...

shall update if i remember more :)

cheers

NaBH4 is used to reduce carbonyl compounds to alcohols without affecting the double bonds. They don't affect Nitro groups as well

LAH reduces keto, aldehyde, and ester but does not affect double bonds

ramkumar_november

B₂H₆ selectively reduces acid in the prescence of ester or keto group

sivaramakh

dibal h does not reduce doublebon carbons but reduces c=o bond specificaly
