Most vitamins can be classified as either fat soluble, which results in their tendency to accumulate in the body (so that taking too much can be harmful), or water soluble, which results in their tendency to be quickly eliminated from the body in urine. Examine the structural formulas and space-filling models of these vitamins and determine whether each one is fat soluble (mostly nonpolar) or water soluble (mostly polar). (a) vitamin C

Hi everyone here we have a question asking us to classify the following molecule as water or fat soluble. Water is a polar molecule. That is a non polar molecule and if we remember correctly, likes dissolve like so if it's polar it'll be water soluble and if it's non polar it will be fat soluble. So let's see what we have in the molecule that will point us to polar or non polar. Here we have two amid groups here we have a carbonnel group and here we have a car box silic acid group. All of these groups are polar because of the difference in electro negativity is between the elements. So overall this molecule is polar and therefore water soluble. And that is our final answer. Thank you for watching. Bye!
