True or False: {eq}\rm CH_3CH_3 {/eq} is the conjugate acid of {eq}\rm CH_3CH_2^- {/eq}

Question:

True or False: {eq}\rm CH_3CH_3 {/eq} is the conjugate acid of {eq}\rm CH_3CH_2^- {/eq}

Components of Neutralization Reactions:

Every neutralization reaction consists of the same substances: an acid and a base on the reactants' side and a conjugate acid and a conjugate base on the products' side. Conjugate acids and conjugate bases act as acids and bases in the reverse reaction.

Answer and Explanation: 1

The statement is true. {eq}\rm CH_3CH_3 {/eq}, which is named ethane, is an acid, albeit a weak one. That means that when ethane donates a hydrogen ion, leaving behind an ethyl residue, which has the formula of {eq}\rm CH_3CH_2^- {/eq}. This is the same formula as the compound in question. When we look at that compound, we see that it is unstable because it is an organic compound with a carbon atom that has extra electrons. Therefore, this compound is willing to accept protons, making it a Bronsted-Lowry base. When this base accepts a proton, it produces ethane, which is the conjugate acid of the Bronsted-Lowry base.
