• A. retention in configuration
• B. inversion in configuration
• C. racemization
• D. mutarotation

Answer 1

The Correct Option is C

$2$-bromobutane reacts with $OH ^{-}$in $H _{2} O$ to give $2$-butanol.
The reaction involves racemization.

Answer 2

Ans. According to the definition, racemization is "the direct conversion of an optically active chemical, either dextro or levorotatory, into a racemate." Resolution is the division of a racemic change into its individual enantiomers. If a sufficient route for enantiomer interconversion is available, racemization—a thermodynamically beneficial process—occurs spontaneously.

A sample of a chiral molecule that has a 1:1 combination of enantiomers is referred to be racemic. Racemicization will ultimately develop. a sample whose enantiomeric excess decreases throughout a reaction (A) or a stereocenter whose configurational purity decreases during a reaction (S).

The process of racemization involves transforming half of a substance's dextro form into its levo form, resulting in a mixture that is optically inactive since the two enantiomers are present in equal amounts. Several things can lead to racialization.

• Heat action: Heat action usually produces racemic mixes from optically active enantiomers.
• Chemical reagents can also be activated by the presence of foreign substances.
• The process of auto-racemization can also be carried out by just allowing the chemical to sit at room temperature for some time.

The functional groups of a compound's molecule can be in either the right or left position at the same time. In a molecular structure, their orientation may differ in the same carbon position. Both molecules have nearly identical chemical characteristics. A racemate or racemic mixture is a combination of these two substances.

The quantity of two enantiomers in the combination is equal in racemate chemistry. The term derives from Louis Pasteur, who was the first to recognize the combination. He discovered that racemic acid has two forms of isomers. Tartaric acid is another name for it. The word 'racemic' derives from the Latin word 'racemus,' which means grape cluster. Tartaric acid is the name for the right-oriented molecule.
