- For each of the following molecules, complete the Lewis structure and use the VSEPR model to determine the bond angles around each central atom. Note that the drawings are only skeleton structures and may depict the angles incorrectly.Use the Lewis dot structure (make sure you show all electron pairs) to predict the electronic geometry_(EG) and the shape of the molecule H2O. O EG - bent; shape - bent O EG - trigonal planar; shape lincar O EG- tetrahedral; shape - bent O EG - tetrahcdral; shape trigonal pyramidal O EG - trigonal bipyramidal; shape - tetrahedralAs you go from HF to HI, does the H—X bond become moreor less polar?

Answer the following questions: The number of C-H bonds The number of N-H bonds The number of C-C bonds = The number of C-N bonds = PreviousWhich one of these statements is NOT TRUE? O The steric number determines the canonical shape of the molecule, which is called the electron-domain geometry. The energy of a molecule is lowered if the repulsions between bonding & nonbonding electron pairs are minimized for all atoms in the molecule. O Nonbonding electron pairs on an atom repel each other electrostatically, but bonding pairs do not. O In VSEPR theory, all of the electron pairs centered on an atom are placed as far as possible from each other in three dimensions. O The shape of the molecules is determined by the geometry of the electron domains.
- What happens when a sample of liquid methanol, CH3OH, is irradiated with infrared (IR) radiation? O IR radiation is not sufficient to excite electrons, so all wavelengths of IR will pass through the sample without getting absorbed in any manner. O Certain wavelengths of IR radiation excite specific molecular vibrations, including bond stretch, bend, wag, rock, and twist vibrations. Electrons in the bonding orbitals of CH3OH absorb the excited to the corresponding antibonding orbitals, resulting in the destabilization of the molecule. radiation and are O Molecules with polar bonds cannot absorb IR radiation, so the IR radiation will be reflected by the sample of methanol.Determine the molecular shape of each of the following species.
