# Hydride Donating Ability [closed]

We know that some compounds can donate $\ce{H-}$ anion to attain stability. What are the conditions under which it occurs and what should be the extent of stability of the product for this pathway to be viable?

• Only some anionic intermediates do that AFAIK. – Mithoron Aug 3 '17 at 21:45

• t-butyl carbocation won't release $\ce{H-}$. – orthocresol Aug 19 '17 at 10:43
