galina1969 [7]

The reaction as shown is known to be an exothermic reaction.

<h2>Endothermic and exothermic reaction:</h2>

Depending on the temperature of the reaction vessel after reaction, the reaction could be classified as;

  • Endothermic
  • Exothermic

In an endothermic reaction, heat is absorbed and the rate of reaction increasing with increase in temperature while in an exothermic reaction, the rate of reaction decreases with increase in temperature.

Hence, the correct statements are;

  • The reaction is an exothermic reaction.
  • The value of K decreases as the value of T increases.

When optically active (R)-2-methylcyclohexanone is treated with either aqueous base or acid, racemization occurs. Explain.
IrinaK [193]

Answer:

See explanation

Explanation:

Racemization is said to occur when a 1:1 ratio of (+) and (-) enantiomers of a compound are produced in a reaction.

The reaction of optically active (R)-2-methylcyclohexanone with either aqueous base or acid leads to the formation of a planar enol species for reaction with acid and a planar enolate species for reaction with base.

Both reactions involves the formation of achiral species which reverts back to the chiral product with equal chances of the formation of both enantiomers of the product during the process. This leads to racemization of the product in both cases.
