Homework Answers
although the benzoin molecule contains one chiral center, yet the product produced in this reaction is not optically active.
this is because the product which is formed is not enantiopure product rather the product is a racemic mixture of two enantiomers. Racemic mixture is the mixture which contain equal amount of two enentiomers so that their optical rotation cancel each other and the product produced is optically inactive.
in this case racemic products formed ( a mixture of R and S configuration product) so the product is not optically active.

Identify the chirality center (sometimes called chiral atom) in each molecule.Okay, so I do understand the meaning of Chirality center or chiral atom. However, I don't know which one is chirality center or not. I thought that Carbon at theend of each molecule are chiral atom, but they are not. So, I do not know which one is chiral atom or not.
