This section contains multiple questions. Each question contains STATEMENTS 1 (Assertion) and STATEMENT 2 (Reason). Each question has 4 choices (A), (B), (C), and (D), out of which ONLY ONE is correct. (A) Statement 1 is True and statement 2 is True; statement 2 is correct explanation for statement 1. (B) Statement 1 is True and statement 2 is True; statement 2 is not a correct explanation for statement 1. (C) Statement 1 is True and statement 2 is False. (D) Statement 1 is False and statement 2 is True. Statement 1: Addition of hydrogen chloride to 1-butane in the presence of organic peroxide gives 2-chloro butane. And Statement 2: The addition reaction involves free radical mechanism.

Peroxide effect is shown only by HBr and it follows free radical mechanis. But if we take peroxide with HCl or HI or even wit HF there will no effect on it. The main thing to remeber is that reaction of HX with alkene (X=F,Cl,Br,I) always follows ionic mechanism and carbocation will be generated, though we take peroxide or not. But in case of Br peroxide leads to free radical mechanism.

 

   Do not go in the tricks like markonikov rules follwo mechanism and form product according to stability of carbocatin because carbocation can rearrange.
