Question:

Which is more acidic, an sp2 C-H proton, or an sp C-H proton, and why?

Answer:

The sp H is more acidic because in an sp hybrid, electrons are generally held closer to the nucleus due to more s character in the hybrid. Thus, the proton is removed more easily.

Answer:

This rule generally applies to organometallic compounds, in particular Fe, Cr, Mn, and Co. Essentially, it parallels the 8 electron rule for rows 1-3 of the periodic table. If a metal has 18 electrons in its valence shell, it has achieved a noble gas configuration.
