Give molecular formulas corresponding to each of the following ball-and-stick molecular representations (red = O, gray = C, blue = N, ivory = H). In writing the formula, list the elements in alphabetical order. (a) Alanine (an amino acid)

Hi everyone here we have a question telling us that a three D model of a compound is shown below. White spheres represent hydrogen gray represents carbon red, represents oxygen and blue represents nitrogen. And our goal here is to identify its molecular and structural formula. So let's see what we have. We have 12 gray. So we have to carbon. We have white. So we have seven hydrogen. We have one blue, so we have one nitrogen. We have one red, so we have one oxygen. So our molecular formula is C. Two, age seven N. O. Now let's figure out our structural formula. So we see we have one, two Groups of Ch three. So that will be CH three two and then we have our N. O. H. Here. So N O. H. So that is our molecular formula and that is our structural formula. Thank you for watching. Bye.
