Why do JLPT N2 learners confuse 申し訳ない with 若々しい?

Both words occupy adjacent semantic territory, which is exactly why the JLPT uses them as distractors for each other on multiple-choice items. The fastest way to stop confusing them is to study them as a pair, write a one-sentence contrast in your own words, and drill the pair specifically rather than each word in isolation.

Is 申し訳ない or 若々しい more common on JLPT N2?

Both appear in the JLPT N2 curriculum and either may show up on a given exam. Don't try to predict which one the test will choose — learn to distinguish them and you'll be safe regardless. Both belong to the General Adjectives (2) theme of N2 vocabulary.

申し訳ない vs 若々しい

Q: What's the difference between 申し訳ない and 若々しい?

申し訳ない (もうしわけない) means "inexcusable, I am sorry" and 若々しい (わかわかしい) means "youthful, young". Both are polite i-adjectives used in social contexts. A learner might confuse the 'apologetic' 申し訳ない (sorry) with the 'youthful' 若々しい because both function as formal descriptors of a person's state.
