HW 3.41 part c)

Postby Faisal Alshamaa - 1L » Thu May 17, 2018 7:17 pm

Hello, I have a quick question about part c in hw 3.41
Write the complete Lewis structure for each of the following compounds:(c) glycine, H2C(NH2)COOH, the simplest of the amino acids, the building blocks of proteins.

So I was wondering if the chemical formula helps us in determining the groupings of the lewis structure and if its always structured like that. For example, the (NH2) tells us that two hydrogens are bonded to the nitrogen and that the COOH has 2 oxygens and a hydrogen bound to a C (same goes for the H2C, which tells us that two hydrogens are bound to C.)

Thank you!

Yes, a lot of complex organic molecules are structured like this. This is because organic molecules may contain certain "functional groups" that give the molecules specific properties. For example, COOH is a carboxyl group and NH2 is an amino group. Writing the groups separately in the chemical formula helps us identify these groups in the ion.
