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.
Drugs are small molecular weight compounds (<500) that in moderate doses show a therapeutic (beneficial) effect and in high doses show harmful effects. They interact with the macromolecular targets (carbohydrates, proteins, fats and nucleic acid) to produce a biological response.
Identify the monochlorination product of isomeric alkane C5H12Among the isomeric alkanes of molecular formula C5H12, identify the one that on photochemical chlorination yieldsi) A single monochloride | ||||||||||
Identify the types of Hydrogen (equivalent and non-equivalent set)Using symmetry planes and axis of rotation, identify the number of set of equivalent and non-equivalent Hydrogens.

Types of Equivalent Hydrogens (structurally and chemically similar)The Hydrogens attached to a Carbon atom are said to be equivalent if they are in a same chemical environment. Same chemical environment means that under a reaction condition, these hydrogens would lose their identities of being attached to separate Carbons and behave like an identical set. | ||||||||||
