To determine two different alkynes yield 2-butanone from hydration with H 2 O, H 2 SO 4 , and HgSO 4 . Concept introduction: Addition of H 2 O to an alkyne resembles similar to the acid-catalyzed addition of H 2 O to an alkene . In the presence of strong acid or Hg 2+ catalyst, the elements of H 2 O add to the triple bond, an initial addition product of an enol is formed, which is an unstable product and rearranges to a product containing a carbonyl group-that is, a C=O. A carbonyl compound having two alkyl groups bonded to the C=O carbon is called a ketone product as shown below in the fig.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C = O, as their functional group. The carbonyl group in ketones is placed somewhere in the middle of the molecular structure, which means, the C=O is attached to two alkyl groups or benzene rings. Just like all other homologous series, the naming of ketones is done using a common suffix “-one”. The general molecular formula is C n H 2n O. Functional group of a ketone

Interpretation Introduction

Interpretation:

To determine two different alkynes yield 2-butanone from hydration with H₂O, H₂SO₄, and HgSO₄.

Concept introduction:

Addition of H₂O to an alkyne resembles similar to the acid-catalyzed addition of H₂O to an alkene. In the presence of strong acid or Hg²⁺catalyst, the elements of H₂O add to the triple bond, an initial addition product of an enol is formed, which is an unstable product and rearranges to a product containing a carbonyl group-that is, a C=O. A carbonyl compound having two alkyl groups bonded to the C=O carbon is called a ketone product as shown below in the fig.
