1.	Describe the mcchanism of addition of HBr to propene,
Answer» SOLUTION :Mechanism of addition of HBr - to PROPENE : Addition of HBr to propene FOLLOWS markownikoff rule. This can be explained as follows. Mechanism : Step : 1 Formation of electrophile : In H - Br, Br is more electronegative than H. therefore it BREAKS to give `H^(+)` ion and `Br^(-)` ions. The `H^(+)` ions are ATTRACTED towards the doubled bond to form carbocation. Step : 2 Secondary carbocation is more stable than primary carbocation and it predominates over the primary carbocation. Step : 3 The `Br^(-)` ion attack the `2^(@)` carbocation to from 2 - Bromobutane, the major product.
