Q. 734.2( 5 Votes )

An organic compound A (molecular formula C₂H₄O₂) reacts with Na metal to form a compound B and evolves a gas which burns with a pop sound. Compound A on treatment with an alcohol C in the presence of a little of concentrated sulphuric acid forms a sweet-smelling compound D (molecular formula C₃H₆O₂). Compound D on treatment with NaOH solution gives back B and C. Identify A, B, C and D.

Class 10th Lakhmir Singh & Manjit Kaur - Chemistry 4. Carbon and Its Compounds

Answer :

A is ethanoic acid (CH₃COOH) ; B is sodium ethanoate (CH₃COONa); C is methanol (CH₃OH) and D is methyl ethanoate (CH₃COOCH₃).

PREVIOUSAn organic compound A having the molecular formula C3H8O is a liquid at room temperature. The organic liquid A reacts with sodium metal to evolve a gas which bums causing a little explosion. When the organic liquid A is heated with concentrated sulphuric 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 catalyst to form compound C which gives substitution reactions with chlorine. (a) What is compound A? (b) What is compound B? (c) What type of reaction occurs when A is converted into B? (d) What is compound C? (e) What type of reaction takes place when B is converted into C?NEXTWhich of the following hydrocarbons can decolourise bromine water and which cannot? Why? C6H12, C6H14, C6H10
