Identify A and B

On reaction with Cl_2 phosphorus forms two types of halides ‘A’ and B’. Halide A is yellowish-white powder but halide ‘B’ is colourless Oily liquid. Identify A and B and write the formulas of their hydrolysis products.

A non-metal A is an important consituent of our food and forms two oxides B and C. Oxide B is toxic where as C causes global warming. Identify A,B and C?

An alkali metal A gives a compound B on reacting with water. The compound B gives a soluble compound C on treatment with aluminium oxide. Identify A,B and C and give the reactions involved.

A hydrocarbon ‘A’ (C_4H_8) is added with HBr in accordance with Markovnikov’s rule to give compound ‘B’ which on hydrolysis with aqueous alkali forms tertiary alcohol ‘C’ (C_4H_10O) . Identify A, B and C.

Salt ‘A’ commonly used in bakery products on heating gets converted into another salt ‘B’ which itself is used for removal of hardness of water and a gas ‘C’ is evolved. The gas ‘C’ when passed through lime water, turns it milky. Identify A, B and C.

Identify A,B,C and D in the given table: ,

Identify A, B, C and D: (i) CH_3CH_2Br overset (KCN) rarr A overset (LiAlH_4) rarr B

An element A reacts with water to form a compound B which is used in white washing. The compound B on heating forms an oxide C which on treatment with watr gives back B. identify A, B and C and give the reacitons involved.

An organic compound ‘A’ having molecular formula C_4H_8 on treatment with dil. H_2SO_4 gives B. B on treatment with conc. HCl and anhydrous ZnCl_2 gives secondary halide C. Write all the reactions and identify A, B and C.

Identify A, B, C and D in the following conversions: A overset (NaNO_2 //HCl) underset (0-5^@ C) rarr CH_3OH overset (PCl_3) rarr B overset (KCN) rarr C overset (LiAlH_4) rarr D
