(a)
Interpretation: The bond angles and geometry of the highlighted atom needs to be predicted using the VSEPR model.
Concept Introduction: According to VSEPR model, geometry and bond angles of an atom can be determined from its hybridization which can be determined from the number of bond pairs and lone pair of electrons associated with it.
The Lewis structure of compound plays an important role here as it involves the arrangement of valence electrons which tells about the actual number of bond pair and lone pair present in an atom.
(b)
Interpretation: The bond angles about each highlighted atom needs to be predicted using the VSEPR model.

- In Chapter 6, we study a group of organic cations called carbocations. Following is the structure of one such carbocation, the tert-butyl cation. (a) How many electrons are in the valence shell of the carbon bearing the positive charge? (b) Using VSEPR, predict the bond angles about this carbon. (c) Given the bond angle you predicted in (b), what hybridization do you predict for this carbon?arrow_forwardA student who missed this class needs to know how to predict the bond angles and shape of a molecule from looking at its line representation. Write a concise but complete explanation for this student.arrow_forwarddo last two rows only!arrow_forward

- 14. While there are only a few basic VSEPR shapes based on electron geometry, many different VSEPR shapes can arise from different combinations of peripheral atoms and lone pairs. One such shape is the see-saw, which happens when you have a molecule of the general form AXE (where A is the central atom, X is a peripheral atom, and E is a lone pair of electrons). Draw a molecule that would have a see-saw shape (it's not important whether the molecule technically exists, but that it could exist based on the valence electrons of its atoms).arrow_forwardDraw a bond-line structure that best matches the molecule below. (White = hydrogen; yellow = fluorine; green = chlorine; red = bromine)arrow_forwardExplain what is wrong with each molecular geometry and provide the correct molecular geometry, given the numbers of lone pairs and bonding groups on the central atom. Match the words in the left column to the appropriate blanks in the sentences on the right. a bent a trigonal bipyramidal an octahedral a trigonal planar a square planar a trigonal pyramidal a tetrahedral a seesaw a linear In structure (a), four pairs of electrons give cause lone pair-bonded pair repulsions and would have Reset electron geometry. The lone pair would molecular geometry. Help In structure (b), five pairs of electrons give electron geometry. The lone pair occupies an equatorial position to minimize lone pair-bonded pair repulsions, and the molecule would have molecular geometry. In structure (c), six pairs of electrons give electron geometry. The two lone pairs would occupy opposite positions to minimize lone pair-lone pair repulsions, and the molecule would have molecular geometry.arrow_forward
