HALOALKANES AND HALOARENES
A hydrocarbon C5H10 does not react with Chlorine in dark but it gives a single monochlorocompound C5H9Cl in bright sunlight. Identify the hydrocarbon.
Few reagents such as Hydrogen Halides (HX), Sulfuric Acid (H2SO4), Alcohols (R-OH), Water (H2O) follow Markovnikov's Rule for the addition across the double bond of an alkene. But HBr in the presence of a peroxide shows a behavior opposite to the Markovnikov's rule, thereby termed as The Anti-Markovnikov's Rule. It was studied extensively by Morris Kharash was also known as the Kharasch effect or the Peroxide Effect. This behavior is shown only by HBr and not HF, HCl, HI even in the presence of the peroxide. In the absence of the peroxide, HBr adds as per the Markovnikov's Rule.
