WebNov 25, 2015 · 1 Answer Truong-Son N. Nov 25, 2015 Since for every atom that can exist in more than one configuration, you have R or S ( sp3 ), or E or Z ( sp2 ), you have two configurations for each of those atoms. If you had 2 of those atoms, then you have 4 configuration combinations: ( R, R ), ( R, S ), ( S, R ), ( S, S ). WebA good rule of thumb is that a chiral carbon has four distinct substituents (you can't have more than four anyway). This structure has no such carbon: every carbon has at least two hydrogen atoms attached. None is chiral. b) 3-pentanol: This one has none either. red guard company https://adl-uk.com
