WebAug 31, 2024 · Threonine has two chiral centers. The correct options are c. carbon b and d. carbon c . Explanation: Chiral centers are those that have four different groups of atoms bonded to it. Carbon a has three atoms of hydrogen attached to it so it can't be a chiral carbon. It isn't the carboxyl carbon either since it is double bonded to oxygen.
