17. A. PCl3 and BrF3 will have a trigonal pyramidal geometry.
B. Electron pairs geometry: the total number of electron domains is 5.
Molecular geometry: trigonal bipyramidal.
Number of lone pair of electrons = 2
Bond angle = 175o
Polar because of asymmetric charge distribution around the central atom.
18: Valence bond theory predicts that sulfur will use sp2 hybrid orbitals in SO2.
VSEPR theory would suggest that the molecule is bent at about 120o because of the single lone pair on sulfur and hence sulfur exhibits sp2 hybridization, since sp2 hybridization indicates trigonal planar electron pair geometry with 120 degree bond angles.
19. Phosphorus uses sp³ orbitals in PCl.
Based on VSEPR Theory, this is an AX ion with 4 bonding pairs and no lone pairs. Using the orbital geometry, one can predict the hybridization.Here the bonds are pointed toward the 4 corners of a regular tetrahedron. Orbitals that point toward the corners of a regular tetrahedron are sp³ hybridized.
20. Bromine uses sp3d2 hybrid orbitals in BrF5.
Hybridisation of BrF5 is sp3d2 with five bonds and one lone pair on the central atom.
21. Xe is sp3d2 hybridized in Xe(O)F4.
Hybridisation of XeOF4 is sp3d2 . 8 valence electrons are coming from the xenon atom, 6 valence electrons are coming from the oxygen atom and 7 valence electrons from each of the four fluorine atoms. 5 bonding pair of electrons with one lone pair.
22. According to valence bond theory, the triple bond in acetylene (C2H2) consists of one bond and two bonds.
23. A molecule with the formula AX3E uses sp3 orbitals to form its bonds.
24. Valence bond theory predicts that carbon will use sp2 hybrid orbitals in the carbonate anion, CO32-.
The carbonate ion, CO32- has a trigonal planer geometry and hence the carbon is sp2 hybridized. Carbon has three sigma bonds to three oxygen atoms and an unhybridized p-orbital to overlap a p-orbital from oxygen.
25. Valence bond theory predicts that tin will use sp3d hybrid orbitals in SnF5-
26. What is the molecular shape, angle and polarity of A: ClF3 B: XeF2 C: PF6- D: SCl2
A: ClF3: Trigonal bipyramidal with a bond angle of 175oand it is a polar compound.
B: XeF2: Linear with a bond angle of 180o and it is a non-polar compound.
C: PF6-: Octahedral with a bond angle of 90oand it is nonpolar because both its electronic and molecular geometry are octahedral, and as such, it enjoys symmetry with no lone pairs, thus rendering the molecule nonpolar.
D: SCl2: Bent with a bond angle of 104.45o and it is a polar molecule. It contains two pairs of electrons and two polar bonds, which confer a net dipole moment on the molecule due to their geometric arrangement.
