I've read that Tollen's reagent gives a positive test with α-hydroxyl test . I googled it and found that α-hydroxyl ketones get converted into di-ketones.

Q.1 Why other reagents such as Benedict's or Fehling's do not give a positive test with α-hydroxyl test?

Ans. - Previously I thought, Tollen's reagent should be a better oxidising agent. I did the math, and my prediction is correct.
Is this the reason?

Q.2 What if the α-carbon is 3° ? eg.
3-hydroxy-3-methyl-2-butanone

I think, it will not give a positive test.
