Some reactions of propane are given: Hydrogen atoms are substituted one by one, in presence of sunlight. When heated in the absence of air, it decomposes to hydrocarbons with lesser molecular mass. Combines with oxygen to give CO_2 and H_2O .: Identify the type of reactions in each case.

Calculate the molecular mass of the following. (i) H_2O (ii) CO_2 (iii) CH_4

Consider the following metallurgical processes in 1. Heating impure metal with CO and distilling the resulting volatile carbonyl boiling point 43^@C and finally decomposing at 150^@ to 200^@C to get the pure metal. II. Heating the sulphide ore in air until a part is converted to oxide and then further heating in the absence of air to let the oxide react with unchanged sulphide. III. Electrolysing the molten electrolyte containing approximately equal amounts of the metal chloride and CaCl_2 to obtain the metal. The processes used for obtaining sodium, nickel and copper are respectively

C_(12)H_(22)O_(11) , CH_(3)CH_(2)COOH , CH_(3)CH_(2)Cl , CH_(3)CHO , CH_(3)CH_(2)CH_(2)OH , CH_(3)OCH_(3) when we react two compound among the given organic compound in the presence of sulphuric acid, a fragrant product is produced. 1. Choose the organic compounds which produced fragrant products after after reactions. 2. Write the chemical equation fo this reaction.

Some hints regarding a hydrocarbon is given below. i) There are 5 carbon atoms in its main chain. ii) A double bond is there in between first and second carbon. iii) One methyl group is branched at the third carbon atom. a) Give the structural formula of the compound. b) To which family does it belong?

Based on the given equation write down the answers. 2H_2+O_2rarrH_2O : How many moles of Oxygen is needed for the reaction with one mole of Hydrogen?

Rate of a reaction is the change in concentration of any one of the reactants or any one of the products in unit time. 2HI to H_(2)+I_(2) Whether the molecularity and the order of the above reaction are the same? Give reason.
