Question

CH 3- CH = CH 2+ NOCl arrow P Identify the adduct: (A)  (B)  (C)  (D)

Tardigrade Admin · Accepted Answer

The structure of the adduct can be determined on the basis of electrophilic addition of the reagent

N O^{+} C l^{-}

to the alkene. The reaction proceeds in accordance with Markovnikov's rule, where in, the negative part (i.e.,

C l^{-}

) of the reagent is added to the carbon atom having lesser number of hydrogen atoms and the positive part goes to the carbon having more number of hydrogen atoms.

C H_{3} - C H = C H_{2} + NOCl \to C H_{3} - C ∣ l C H - NO ∣ C H_{2}

(i)

NOCl ⇌ N O^{+} + C l^{-}

(ii)

C H_{3} - C H = C H_{2} + N O^{+} \to C H_{3} - C H - N ∣ O C H_{2}

(stable carbocation)
