Final answer:
Two organic compounds result from the oxidative cleavage of 3-heptyne when heated in basic aqueous KMnO₄: propionate (CH₃CH₂CO₂-) and butyrate (CH₃CH₂CH₂CO₂-). These compounds correspond to propionic acid and butyric acid, respectively, in their deprotonated carboxylate anion forms.
option c is the correct
Step-by-step explanation:
When 3-heptyne is heated in basic aqueous KMnO₄, the reaction that occurs is called oxidative cleavage. This reaction involves breaking the carbon-carbon triple bond and forming two smaller molecules.
Potassium permanganate (KMnO₄) in a basic aqueous solution will oxidize the alkyne to carboxylate anions. The position of the triple bond in 3-heptyne means it is between the third and fourth carbon atoms. As a result, the broken bonds are replaced with bonds to oxygen, leading to the formation of two carboxylic acids.
Therefore, heating 3-heptyne with KMnO₄ yields propionic acid (CH₃CH₂CO₂H) and butyric acid (CH₃CH₂CH₂CO₂H). However, under the basic conditions, these products will predominantly exist as their carboxylate anion forms, propionate (CH₃CH₂CO₂-) and butyrate (CH₃CH₂CH₂CO₂-). The following are the correct organic compounds that result from this reaction:
The other options listed do not correspond to the oxidative cleavage products of 3-heptyne.
