Question

question 10 (1 point) which of the following is the strongest (most reactive) base? -ch₃⁻ -nh⁻ -o⁻

Explanation:

The strength of a base depends on its ability to accept a proton. A carbanion ($-\text{CH}_3^-$) is the strongest base among the options as carbon is less electronegative than nitrogen and oxygen. The less electronegative an atom, the more willing it is to donate its electron - pair and accept a proton. The other species have more electronegative atoms (N or O) which hold the negative charge more tightly, making them less basic. The amide and carboxylate ions have resonance stabilization which further decreases their basicity.

Answer:

$-\text{CH}_3^-$ (the first option)
