A hydrocarbon (V.D. = 27) containing C = 88.88% decolourised `KMnO_4` solution and bromine water with evolution of HBr. It gave no precipitate with either ammoniacal silver nitrate or cuprous chloride solution. When treated with dil. `H_2 SO_4` in the presence of `HgSO_4`, it gave methyl ethyl ketone. What is the hydrocarbon ?

A hydrocarbon decolourizes KMnO_4 solution but does not form any precipitate with either ammoniacal AgNO_3 or Cu_2Cl_2 . Is the hydrocarbon saturated or unsaturated?

A hydrocarbon decolourizes KMnO_4 solution but does not form any precipitate with either ammoniacal AgNO_3 or Cu_2Cl_2 . Does the hydrocarbon belong to alkane, alkene or alkyne family?

A hydrocarbon decolourizes KMnO_4 solution but does not form any precipitate with either ammoniacal AgNO_3 or Cu_2Cl_2 . What is the type of bonds between two C atoms-single, double or triple?

When a salt is heated with dil H_(2)SO_(4) and KMnO_(4) solution the pink colour of KMnO_(4) is dicharged, the mixture may contain

An alcohol A, when heated with conc. H_(2)SO_(4) gives an alkene B. When B is bubbled through bromine water and the product obtained is dehydrohalogenated with exccess of sodamide, a new compound C is obtained. The compound C gives D when treated with warm dilute H_(2)SO_(4) in the presence of HgSO_(4) . D can also be obtained either byh oxidising A with KMnO_(4) or form acetic acid through its calcium salt. Identify A, B, C, and D.

When V ml of 2.2 M H_(2)SO_(4) solution is mixed with 10 V ml of water, the volume contraction of 2% take place. Calculate the molarity of diluted solution ?

An impure sample of sodium chloride which weighed 1.2 g gave on treatment with excess of silver nitrate solution 2.4g of silver chloride as precipitate.Calculate the percentage purity of the sample

An aqueous solution of a mixture of two inorganic salts when treated with dilute HCl, gave a precipitate (P) and a filtrate (Q). The precipitate (P) was found to dissolve in hot water. The filtrate (Q) remained unchanged, when treated with H_(2)S in a dilute mineral acid medium. However, it gave a green precipitate (R) in with H_(2)S in ammoniacal medium. The precipitate (R) gave a coloured solution (S), when treated with H_(2)O_(2) in an aqueous NaOH medium. The coloured solution (S) contains

A chloro compound (A) showed the following properties, i. decolourised bromine in CCl4 (ii). Absorbed hydrogen catalytically. (iii). Gave a red precipitate with ammoniacal cuprous chloride (iv). When vaporised 1.49 gm of (A) gave 448 ml of vapours at STP. Identify (A) and write the equation for the reaction is step 3.
