Deviation from Ideal Bond Angles

Thus, for similar molecules within a given electron-group arrangement, electron-pair repulsions cause deviations from ideal bond angles in the following order ... 

FOLLOW-UP PROBLEM 10.8 Determine the shape around each central atom and predict any deviations from ideal bond angles in the following (a) H2SO4 (b) propyne (C3H4 there is one C=C bond) (c) S2F2. 

Describe the five electron-group arrangements and associated molecular shapes, predict molecular shapes from Lewis structures, and explain deviations from ideal bond angles ( 10.2) (SPs 10.6-10.8) (EPs 10.25-10.49)... 

Determine the shape around each central atom in each molecule, and explain any deviation from ideal bond angles ... 

Lewis structure for each, determine the shape around each carbon, and predict any deviations from ideal bond angles. 

Qualitative prediction of deviations from ideal bond angles can be made by taking into account the differences of the sizes and shapes of the electron pair domains in a valence shell. The electron pair domains in a valence shell are not all equivalent for the three important reasons ... 

Angle sttain is the result of deviation from ideal bond angles caused by inherent structural constraints (such as ring size). 

In addition to propyne (see Follow-up Problem 10.8), there are two other constitutional isomers of formula C3H4. Draw a Lewis structure for each, determine the shape around each carbon, and predict any deviations from ideal bond angles. 

Determine the molecular geometry about each central atom and label all the bond angles. Cite any expected deviations from ideal bond angles. 

Which of the following shows a deviation from ideal bond angles that is not possible for an AB. molecule ...
