WebIt is difficult to replace chlorine with -OH in chlorobenzene in comparison to that in chloroethane. Reason (R): Chlorine carbon (—Cl) bond in chlorobenzene has a partial double bond character due to resonance. 1. Both (A) and (R) are true and (R) is the correct explanation of (A). WebThe addition of HBr to propene yields 2-broniopropane, while in the presence of benzoyl peroxide, the same reaction yields 1-bromopropane. Explain and give mechanism. An alkene ‘A’ contains three C-C eight C-H bonds, one C - C bond. ‘A’ on ozonolysis gives two moles of an aldehyde of molar mass 44 amu. Write the IUPAC name of ‘A’.

According to this rule, major product is the most substituted alkene i.e., major product is obtained by elimination of H from that ?-carbon which has the least number of hydrogen. Product of the reaction in this case is known as Saytzeff product.
