Determine the dipole direction for carbon tetrachloride (CCl4) based on its geometry and the dipole moments of the individual bonds. Although the C–Cl bonds have a net dipole moment towards the chlorine, these moments cancel each other out because of the (____________) linear or trigonal planar or bent tetrahedral or trigonal pyramidal or trigonal bipyramidal or seesaw or T-shaped or octahedral or square pyramidal or square planar geometry of CCl4. Therefore, CCl4 has __________________ a net or no net dipole moment.
1.) Determine the dipole direction for carbon tetrachloride (CCl4) based on its geometry and the dipole moments of the individual bonds.
Although the C–Cl bonds have a net dipole moment towards the chlorine, these moments cancel each other out because of the (____________) linear or trigonal planar or bent tetrahedral or trigonal pyramidal or trigonal bipyramidal or seesaw or T-shaped or octahedral or square pyramidal or square planar geometry of CCl4. Therefore, CCl4 has __________________ a net or no net dipole moment.
2.) (a) Determine the molecular geometry of SeF4using the VSEPR model.
The molecular geometry of SeF4 is (___________________) linear or trigonal planar or bent tetrahedral or trigonal pyramidal or trigonal bipyramidal or seesaw or T-shaped or octahedral or square pyramidal or square planar .
3.) (b) Explain why the molecular geometry of SeF4 is different from that of IBr3, although they have similar electron-domain geometries.
Although both SeF4 and IBr3 have the electron-domain geometry of (_________________) linear or trigonal planar or bent tetrahedral or trigonal pyramidal or trigonal bipyramidal or seesaw or T-shaped or octahedral or square pyramidal or square planar, IBr3 has _____ lone pair(s) of electrons whereas SeF4 has only ________ lone electron pair(s) in the (______________) axial or equatorial positions. Accordingly, the molecular geometry of SeF4 is (________________) linear or trigonal planar or bent tetrahedral or trigonal pyramidal or trigonal bipyramidal or seesaw or T-shaped or octahedral or square pyramidal or square planar, but that of IBr3 is (__________) linear or trigonal planar or bent tetrahedral or trigonal pyramidal or trigonal bipyramidal or seesaw or T-shaped or octahedral or square pyramidal or square planar.
