(polarization). Thus one end of the molecule becomes slightly negatively charged and the other end slightly positively charged. Br 2 ethene > Br s+ - Br 5 " Step 2 Electrophilic addition The positively charged Br 5+ acts as an electrophile This gets attracted towards the double bond (rc bond) of..

-propane In perhalohydrocarbons all the hydrogen atoms of hydrocarbon are substituted by halogen atoms. (Ex. tetrachloro methane, hexachloroethane, etc.) During additon of HBr to unsymmetrical alkenes, peroxide effect (Kharasch effect) is observed, forming 1" alkylbromides as major produc..

The self linking property of carbon atoms through covalent bonds to form open chain and cyclic compounds is called catenation. Carbon readily combines with other elements like, hydrogen, oxygen, nitrogen, halogens, etc. to form stable covalent bonds. Because of these unique chara..

>OH. In the language of chemistry it refers to a complete homologous series of alcohols. Ethyl alcohol is just one member of this series. Alcohols can be classified according to the number of -OH groups present in the molecule. i. Monohydric alcohols contain one hydroxyl group. Example: E..

Part - D 1 Answer one of the following questions 1 x 10 = 10 35. a. Balance the following equation by oxidation number method. MNO; + Fe 2+ -> Mn ++ + Fe 3+ 4 b. Calculate the volume of carbon dioxide gas liberated at STP by heating lOg of calcium carbonate. ..
