Concept explainers
(a)
Interpretation:
The number of lone pairs on the dark red atom needs to be determined. An example of molecule having this geometry needs to be determined.
Concept Introduction:
Lewis structures can be used to determine the shape around an atom in a molecule. In order to determine the shape of a central atom, first the number of atoms surrounded by it needs to be determined.
The valence shell electron pair repulsion (VSEPR) theory can be used to determine the shape around an atom.
(b)
Interpretation:
Thenumber of lone pair of electrons needs to be determined in the molecule. An example should be given for the type of the molecule.
Concept Introduction:
Molecules follow octet rule and depending on the number of lone pairs in the central atom, they form different molecular shapes.

- Considering each of the given ball-and-stick models: [1] Does the dark red atom have one or more lone pairs of electrons on it? Explain your choice. [2] Give an example of a molecule that has the indicated geometry.arrow_forward3) Determine whether CH3CI is polar. To do this, you must: draw the 3D structure of the molecule, use arrows to indicate polar bonds, and either use an arrow to indicate the net dipole moment or state that the molecule is non-polar.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
