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) The carbon with the smallest delta value (the most shielded) is . The carbon with the largest delta value (the most deshielded) is a

Part 1: The most shielded is c while the least shielded is a.

Part 2: The most shielded is b while the least shielded is a.

Explanation:

As the complete question is not given than the reference question as viewed online is solved and is attached for reference.

Part 1:

The carbon of is most shielded as it is most electronically rich so the answer for most shielded carbon atom is c.

The carbon of carbonyl group is least shielded as Oxygen is the electronegative radical so the answer for most shielded carbon atom is a.

Part 2:

The carbon of is most shielded as it is most electronically rich so the answer for most shielded carbon atom is b.

The carbon of ring is least shielded as due to presence of the pi electrons so the answer for most shielded carbon atom is a.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
