Answer 1

We have to know that reactions in which a more grounded nucleophile replaces a more vulnerable nucleophile are named as the Nucleophilic replacements response. The presence of the little positive charge on the carbon particle makes it defenseless to assault by nucleophilic reagents.

Complete answer:
We have to know that, racemic blend, likewise called racemate, a combination of equivalent amounts of two enantiomers, or substances that have dissymmetric sub-atomic designs that are identical representations of each other. Every enantiomer pivots the plane of polarization of plane-spellbound light through a trademark point, yet, on the grounds that the rotatory impact of every segment precisely drops that of the other, the racemic combination is optically dormant.
A racemate is optically inert, implying that there is no net pivot of plane-captivated light. Albeit the two enantiomers turn plane-spellbound light in inverse ways, the pivots drop since they are available in equivalent sums.
As opposed to the two unadulterated enantiomers, which have indistinguishable actual properties with the exception of the heading of turn of plane-enraptured light, a racemate now and again has various properties from both of the unadulterated enantiomers. Diverse dissolving focuses are generally normal, however various solubilities and limits are additionally conceivable.
To display a racemic combination the compound ought to contain in any event one chiral carbon in the compound. Chiral carbon is a deviated carbon that is appended to four unique kinds of particles or gathering of atoms. But any remaining compound didn't have at any rate one chiral.

Therefore, the compound is I. Hence, the correct option is (A).

Note:
We have to know that drugs might be accessible as a racemate or as the unadulterated enantiomer, which may have various potencies. Since organic frameworks have numerous chiral deviations, unadulterated enantiomers as often as possible have totally different natural impacts; models incorporate glucose and methamphetamine.
