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.$)$

The carbon with the smallest delta value $($the most shielded$)$ is

The carbon with the largest delta value $($the most deshielded$)$ is

The carbon with the smallest delta value $($the most shielded$)$ is

The carbon with the largest delta value $($the most deshielded$)$ is
