1HNMR is a carbonyl group more de-shielding than a C-O? which one would cause the furthest upfield signal?
Homework Answers
The protons which are directly attached with carbonyl group are highly deshielded due to the diamagnetic anisotropy of carbonyl group whereas for the protons which are attached with a carbon (adjacent of Oxygen atom) are only deshielded by the electronegativity of Oxygen atom
Thus former will show the furthest upfield signal.

organic chemistry
A carbonyl group, C=O, and an alkene, C=C, double bonds, are both sp2 hybridized. However, the chemistry of these two functional groups is very different. This can be explained by which of the following statements? a. The bond angle of the carbonyl is larger than the bond angle of the alkene. b. The electronegative oxygen of the C=O group makes this bond polar. d. There is more steric crowding in the carbonyl than in the alkene. Which, if...
