Why boron trihydride is weaker lewis acid than boron tribromide and boron tri-iodide?
There is no back-bonding in case of boron trihydride so it is a stronger lewis acid than boron trichloride ( even though chlorine atom is more electronegative than hydrogen atom).
Then why boron ...

Why is there a charge on COOH⁻¹?
The dissociation of formic acid ($\ce{HCOOH}$) is:
$$
\ce{HCOOH -> H+ + COOH-}
$$
Why is there a charge on $\ce{COOH^{-1}}$
though? Is it achieved through:
$$1\times(\ce{C^{4+}}) + 2\times(\ce{O^...
