The electronegativity is 2.1 for H and 1.9 for Pb.Based on these electronegativities,PbH₄ would be expected to: A)be ionic and contain H^- ions B)be ionic and contain H⁺ ions C)have polar covalent bonds with a partial negative charge on the H atoms D)have polar covalent bonds with a partial positive charge on the H atoms

Question

Quizplus · Accepted Answer

The electronegativity difference between H and Pb is only 0.2, which is not large enough for an ionic bond. PbH₄ is most likely held together by polar covalent bonds, with the H atoms carrying a partial positive charge due to the higher electronegativity of Pb.

The Electronegativity Is 2
