Question

An unsaturated hydrocarbon $X$ on ozonolysis gives $A$. Compound $A$ when warmed with ammonical silver nitrate forms a bright silver mirror along the sides of the test tube. The unsaturated hydrocarbon $X$ is :

• A.
• B.
• C. $C{H}_3-C\equiv C-C{H}_3$
• D. $CH\equiv C-C{H}_2-C{H}_3$

Answer 1

The correct option is D $CH\equiv C-C{H}_2-C{H}_3$

The product 'A' from ozonolysis of X gives silver mirror test with tollen's reagent. Hence, 'A' should be a aldehyde or HCOOH or $\alpha$-hydroxy ketone.





Hence, option (c) is correct.
