1.) Use the VSEPR model to determine the three-dimensional shapes ofcarbon tetraiodide, CI4, and phosphine, PH3.  Circle the correct answer! Choose only 1. CI4:  Linear trigonal planar      bent tetrahedral trigonal pyramidal trigonal bipyramidal seesaw T-shaped Octahedral square pyramidal square planar Circle the correct answer! Choose only 1. PH3:  Linear trigonal planar      bent tetrahedral trigonal pyramidal trigonal bipyramidal seesaw T-shaped Octahedral square pyramidal square planar   2.) Identify the polarity of carbon dioxide (CO2) and water (H2O) based upon its geometry and the dipole moments of the individual bonds. Circle the correct answer! Choose only 1. carbon dioxide: Polar nonpolar         Circle the correct answer! Choose only 1.water: polar nonpolar

One of the following questions is true; the rest are false. Please identify the true statement in the enumeration below.   1. Tetrahedral molecules are more stable than other molecular geometries. 2. Lone pairs are an exception to the rules for Lewis dot structures. 3. A double bond consists of two sigma bonds. 4. Hybridization of atomic orbitals is required to explain molecular geometry. 5. None of the Abov

Which statement is true about antibonding molecular orbitals? All of these are true. Antibonding orbitals form by subtracting (canceling) one another where they overlap. Placing electrons in an antibonding orbital reduces the bond order. It requires less energy to remove an electron from an antibonding orbital compared with removing an electron from the atomic orbital from which the anitbonding orbital forms. Only A and B ate true.
