Carbon is not the only element that can function as a chiral center. In Problem 5.6 we saw an example in which a phosphorus atom is achiral center. In such a case, the lone pair is always assigned the fourth priority. Using this information, assign the configuration of thechiral center in this compound:ORS

The configuration of the chiral center ('P'atom) in the given compound is:SExplanation:

Answered: Carbon is not the only element that can…
