An alkyne with five carbon atoms per mol...

An alkyne with five carbon atoms per molecule when passed through dilute sulphuric acid containing mercuric sulphate gives a compound which forms an oxime but has no effect on Fehling's solution. The compound on oxidation gives dimethyl acetic acid. It reacts with sodamide to form a hydrocarbon. What is the structure of the alkyne ?

AI Generated Solution

To solve the problem step by step, we will analyze the information given in the question and derive the structure of the alkyne. ### Step 1: Identify the Alkyne We know that the alkyne has five carbon atoms. The general formula for an alkyne is CnH2n-2. For n = 5, the formula becomes C5H8. ### Step 2: Reaction with Dilute Sulfuric Acid and Mercuric Sulfate When an alkyne reacts with dilute sulfuric acid (H2SO4) in the presence of mercuric sulfate (HgSO4), it undergoes hydration to form a ketone. The product must be a ketone because the alkyne has five carbon atoms. ...
