The compound below is treated with chlorine in the presence of light. CH3 CH3 [References] CH₂ Draw the structure for the organic radical species produced by reaction of the compound with a chlorine atom. Assume reaction occurs at the weakest C-H bond.

Experimentally, the shape around the highlighted nitrogens is found to be trigonal planar rather than trigonal pyramidal predicted by the Lewis structure above. Sketch a resonance structure that would account for trigonal planar geometry about the highlighted nitrogens in uracil. Add formal charges to the four atoms that have non-zero formal charges. LA O--

What is the relation between these two molecules and how do you explain it

The structure of Vitamin C (ascorbic acid) is shown below. As the name indicates, the molecule is somewhat acidic. Actually, one of the hydrogens on the four OH groups is much more acidic than the other three ones. Which one is the acidic hydrogen? Hints: To find the answer, you will again have to draw some resonance structures of the product formed after loss of H+. Consider the product after the loss of H+ for each of the OH groups. Only two of the OH groups have resonance structures after deprotonation; one of these two groups has a much better resonance structure than the other one (again after deprotonation). Note that the oxygen atom that is part of the five-membered ring has nothing to do with the problem.
