Problem

Monosodium glutamate, often abbreviated as MSG, is a sodium salt of glutamic acid. It is known to intensify meaty, savory flavors in food, and is widely used as a flavor enhancer in the food industry. The Lewis structure for MSG is shown below.
Complete the following statements to describe each bond as nonpolar covalent, polar covalent, or ionic.
the Lewis structure for MSG. Bond 1 is between Na plus and O minus. EN values are 0.9 and 3.5 for Na and O. Bond 2 is between C and H plus. EN values are 2.5 and 2.1 for C and H. Bond 3 is between O and H. EN values are 3.5 and 2.1 for O and H.
Bond 1 is a(n)
