Question

name the phenol having acidic hydrogen​

Answer 1

Answer:

Also, the o-nitro phenoxide ion formed after the loss of protons is stabilised by resonance. Hence, ortho-nitrophenol is a stronger acid while on an attachment of −CH3 group (electron-donating group) acidic strength of phenol is decreased in cresol due to the destabilisation of phenoxide ion.carborane acid

The world's strongest acid, at least a million times more potent than concentrated sulphuric acid, has been made in a lab in California. Perhaps confusingly, it is also one of the least corrosive. The compound, called a carborane acid, is the first 'superacid' that can be stored in a bottle, say its creators.
