If the starting material has no stereogenic centers,when carbonyl compounds are reduced with a reagent such as LiAlH₄ or NaBH₄ and a new stereogenic center is formed,what will the composition of the product mixture be? A)Forms a racemic mixture of the two possible enantiomers B)Forms more of one enantiomer than another because of steric reactions around the carbonyl C)Forms more of one enantiomer than another depending on the temperature of the reaction D)Forms different products depending on the solvent used

When starting with a carbonyl compound that has no stereogenic centers, the reduction with a reagent such as LiAlH4 or NaBH4 will result in the formation of a new stereogenic center. Since the reduction is not stereoselective, both possible enantiomers will be formed in equal amounts, resulting in a racemic mixture. Therefore, choice A is the correct answer.
