Question

$HBr$ fails to give addition products with carbonyl compounds.
Is the above statement true?

• A. True
• B. False

Answer 1

The correct option is A True

The addition of $HBr$ to a carbonyl pi-bond is reversible and heavily favours the reactants thermodynamically, meaning the product is impossible to isolate, but the product is still an important intermediate for a host of other reactions. The reason nucleophile addiction is seen so much more than electrophilic addition is due to the instability of the carbocation compared with the oxygen anion. The above statement is true.
