MCAT Diagnostic, C/P, Q18

Postby NS_Tutor_Katelyn » Tue Jul 31, 2018 4:22 pm

A student asked us: "Sulfur has lower electronegativity than Carbon, so I don't understand why you gave it higher priority in the answer."

Chirality (R/S) is determined by assigning priority based on size (i.e. mass number), not electronegativity.
