Question

Give me some 15 to 20 questions on nomenclature of organic compound fir class 10

Answer 1

Question.1 Draw the electron dot structure of ethyne and also draw its structural formula.



Question.2 A compound X is formed by the
reaction of a carboxylic acid C2H4O2 and an alcohol in presence of a few drops of H2SO4. The alcohol on oxidation with alkaline KMnO4followed by acidification gives the same carboxylic acid as used in this reaction.

(a) carboxylic acid, (6) alcohol and (c) the compound X. Also write the
reaction.
