<span>the behavior of the above pair of substances</span> is soluble
Answer:
D
Explanation:
pressure is inversely proportional to gas volume
Answer:
the stabilization of the negative charge in orbitals with higher s character
Explanation:
Acetylide anion is a carbon anion compound or popularly called carbanion. Now Acetylide anion is sp hybridized. However acetylide anion tends to be more acidic as we move from sp³ to sp, hence acidicity increases, which makes sp to have the highest acidity and become the most stable.
So, we can conclude that the acetylide anion is more acidic due to the stabilization of the negative charge in orbitals with higher s character and as the s character increases, acidic nature of acetylide anion also increases.
These are all group 4 elements, and for these elements, the metallic character increases as we go down the group. Therefore, the answer is:
Pb, Ge, Si, C
