The chemical environment of carbons can be deduced form their chemical shifts. Deduce the relative chemical shifts of the carbons at the labeled positions. (Carbons that are highly shielded have low delta, chemical shift, values.) 1) b он с The carbon with the smallest delta value (the most shielded) is The carbon with the largest delta value the most deshielded) is 2) The carbon with the smallest delta value (the most shielded) is The carbon with the largest delta value the most deshielded) is
