Which family of compounds is most likely to be relatively inert?

Question

a. alcohols

b. ethers

c. sulfides

d. carboxylic acids.

Answer 1

b.Ethers are comparatively inert

Answer 2

I think ethers are the most inert of this group due to their structure.  They are not oxidizers like the acid. They can't donate their hydrogen like the sulfide, or form hydrogen bonds with them like the alcohols.
