(a)
Interpretation:
The electron-pair geometry for each carbon atom in
Concept introduction:
The electron pairs in Lewis diagrams repel each other in real molecule and thus they distribute themselves in positions around the central atoms which are far away from one another. This arrangement of electron pairs is called electron-pair geometry. The electron pairs may be shared in covalent bond, or they may be lone pairs.
(b)
Interpretation:
The molecular geometry prdicted by the valence shell electron-pair repulsion theory for the molecule
Concept introduction:
Molecular geometry is the precise term that is used to describe the shape of molecules and arrangement of atoms around the central atom. The molecular geometry of a molecule is predicted by valence shell electron-pair repulsion theory or in short VSEPR theory. VSEPR theory applies to substances in which a second period element is bonded to two, three, four, or other atoms.

- Classify each of the following statements as true or false: a Molecular geometry around an atom may or may not be the same as electron-pair geometry around the atom. b Electron pair geometry is the direct effect of molecular geometry. c If the geometry of a molecule is linear, the molecule must have at least one double bond. d A molecule with a double bond cannot have trigonal pyramidal geometry around the double bonded atom. e A CO2 molecule is linear, but an SO2 molecule is bent. f A molecule is polar if it contains polar bonds. g A molecule with a central atom that has one lone pair of electrons is always polar. h A molecule with a central atom that has two lone pairs and two bonded pairs of electrons is always polar. i Carbon atoms normally form four bonds. j Hydrogen atoms never form double bonds.arrow_forwardComplete Table 3 (Remember that the values pertain to the Central atoms only.
