     Halogen acids readily combine with alkenes to form addition products but fail to react with carbonyl compounds. Discuss.

    Answer:

                                                                                                   Halogen acids (HX) react with alkenes to form haloalkanes but they fail to react with the carbonyl compounds. In fact, the attack does take place but the product is unstable and decomposes to form carbonyl compound along with halogen acid. Thus, the reaction becomes reversible.
