Expert Solution & Answer
Trending nowThis is a popular solution!
Students have asked these similar questions
1. The electron pair in a H - Cl bond could be considered...
a. closer to H because Hydrogen has a larger radius and thus exerts greater control over the shared electron pair
b. closer to Cl because Chlorine has a higher electronegativity than Hydrogen
c. closer to H because Hydrogen has a lower electronegativity than Chlorine
d. an inadequate model since the bond is ionic
2. It is important to know the geometry of a molecule because the geometry _______.
a. will give the Lewis structure of the molecule
b. affects the physical and chemical properties of the substance
c. will determine whether the molecule is ionic or covalent
d. Both B, and C

A molecule is made from four atoms. The first atom (A) has four valence electrons, the second atom (B) has 6 valence electrons, and the other two atoms (C) each have 7 valence electrons. What is the geometry of the molecule ABC2?
the correct resonance structure are ( a&B, a&c, a&d, b&c, b&d, or c&d). The most important contributer is (H, A, B, C, D) and second most important is (H, A, B, C, D)
