5 PCl 5 trigonal bipyramidal 90°,120°,180° 6 SF 6 octahedral 90°,180° While the number of electron pairs dictates th ...
Solution: The Lewis structure of CO 2 is O=C=O, with two extra lone pairs of electrons on each oxygen ...
However, if the orientation of the bond dipoles is such that they do not cancel out, the molecules will ...
Orbital Hybridization So far we have ignored the fact that the valence electrons that interact originally ...
sp^2 HYBRIDIZATION Three sp^2 hybrid orbitals are formed by mixing an s and two p orbitals. Again, three ...
Sigma and Pi Bonds Going back to the example of BeH 2 , one envisions an sp hybridized orbital overlapping with ...
form a weaker π bond. It is weaker because the overlap is not end-to-end but only side-to-side. You can see ...
Ionic Compounds Covalent Bonds Bond Length Bond Energy Lewis Structures Formal Charge Resonance Structures Excep ...
Review Questions 1 . Consider the following reaction: H 2 (g) + F 2 (g) → 2 HF (g) Is the H—F bond mo ...

IV. 5 . Which is not a resonance form of: (A) I. II. III. (B) I. II. ...
III. 6 . Label formal charges and predict which is the most likely resonance structure for N 2 O: (A) (B) (C) (D) ...
Answer Key REVIEW QUESTIONS 1 . The H—F bond is more polar than an H—H bond. 2 . Cl 2 < HCN < NaC ...
Answers and Explanations REVIEW QUESTIONS 1 . The H—F bond is more polar than an H—H bond. “Polar” denotes uneq ...
II Choices I and III must be wrong because, although they satisfy the octet rule, they have the wrong ...
N: 5 electrons 8 electrons 3 O: 18 electrons 24 electrons 24 electrons 32 electrons (32 – 24) electrons = 8 ...
Now check the formal charges: The P has a formal charge of +1 and the O has a formal charge of –1. These can ...
C. All three are polar. D. H 2 S is angular due to the two lone pairs on S, therefore polar. ...
