Glycine, is an amino acid used in the synthesis of proteins. Its molecular formula is C₂H₅NO₂. Below is a partial arrangement of the atoms of glycine. N C C O 

a. Complete the Lewis structure of glycine by adding the five (5) hydrogens in the structure, lone pair of electrons, and shared pair of electrons. You can use dashes (----) in lieu of shared pairs of electrons, to indicate where the covalent bonds (either single, double, or triple bonds) are formed between the atoms.  

b. What is the shape around the N atom (assume N here as a central atom)? 

c. What is the shape around the O atom that is connected to C on the right most side of the structure (assume O here as a central atom)? 

d. What is the shape around the C that is connected to N (assume C here is the central atom)? 

e. How many lone pairs of electrons are around the O atom in question 12c?  

f. How many lone pairs are around the N atom?

g. How many valence electrons (total) are around the Lewis structure of glycine? 

h. Is glycine a polar or nonpolar molecule? Explain your answer.  

i. How many polar bonds are present in the structure of the glycine molecule? 

j. How many single bonds are present in the Lewis structure of glycine?
