If a student extracts first with NaOH then with NaHCO3, what will be the result?

Doesn't that have something to do with what is being treated?
well the compounds being used are benzoic acid, p-tertbutylphenol and p-dimethoxybenzene!!
I think doing so would extract p-tertbutylphenol first and then benzoic acid because it NaOH is a strong base so it reacts with weak acid first ?? Is that correct?

I think a strong base will react with BOTH the weak acid and the strong acid.

I think you should extract first with NaHCO3, which will remove the benzoic acid but not the phenol. Then extract with the NaHCO3.
If you extract with NaOH first, you form a salt with both the phenol AND the benzoic acid. When you acidify the extract, both benzoic acid and the phenol appear as a mixture. This would separate from the neutral compound, however.
