An organic liquid 'A' containing C,H and O with boiling point `78^(@)C`, possessing a rather pleasant odous. On heating with concentrated sulphuric acid gives a gaseous product 'B' with the empirical formula `CH_(2)` 'B' decolourises bromine water as well as alkaline permanganate solution and takes up one mole of `H_(2)` (per mole of B) in presence of finely divided nickel at high temperature. Identify the substances A and B.

An organic liquid (A), containing C,H and O with the boiling point 78^(@)C and possessing a rather pleasant odour, or heating with concentrated H_(2)SO_(4) gives a gaseous product (B) with the empirical formaula CH_(2) .(B) decoluourises bromine water as well as alkaline KMnO_(4) solution and takes up one mole of H_(2) (per mole of B)in the presence of finely divided nickel at high temperature (A) and(B) are:

An organic liquid A containing C,H and O has a pleasant odour with a boiling point of 78^(@)C . On boiling. A with conc. H_(2)SO_(4) a colourless gas is produced which decolourises bromine water and alkaline KMnO_(4) . One mole of this gas also takes one mole of H_(2) . The organic liquid A is

An organic compound A of molecular formula C_(2)H_(6)O is a constituent of wine and beer. This compound on heating with alkaline potassium permanganate forms another organic compound B which turns blue litmus to red. Identify the compounds A and B.

An organic compoud A having the molecualr formufla C_(3)H_(8)O is a liquid at room temperature .The organic liquid A reacts with sodium metal to evolve a gas which burns causing a little explosion .When the organic liquid A is heated with concentrated suphuyric acid at 170^(@)C it forms a compound B which decolourises bromine water. The compound B adds on one molecule of hydrogen in the presence of Ni as catayst to from compound C which gives substitution rections with chlorine. (a) what is compound A? (b) what is compound B? (c ) What type of reaction occurs when A is converted in to B? (d) What is compound C? (e ) What type of rection takes place when B is converted in to C?

A compound C_(9)H_(7)O_(2)CI exists predominanthly in enol from (A) and also in keto from (B) On oxideation with KMnO_(4) it gives m-chlorobenzoic acid as one of the products. Identify the compounds (A) and (B).

An organic compound A on heating with concentrated H_(2)SO_(4) forms a compound B which on addition of one mole of hydrogen in presence of Ni forms a compounds C. One mole od compound C on combustion form two moles of CO_(2) and three moles of H_(2)O . Identify the compounds A,B and C write the chemical equation of the reactions involved.
