Ammonia (NH3) which has only 1 pair of non-bonding lone pairs electrons which have comparatively lower repulsive force and bond angle is around 107 °. Use the following Lewis structure for acetic acid to answer the following questions: ____ 36. What VSEPR “shapes” and bond angles do you find in Toluene? Write a note on Green Chemistry! Although models cannot show this simply, for molecules like NF3 (whose structure you drew earlier), the actual bond angles may not exactly equal the angles predicted by VSEPR theory. Carbon dioxide (CO 2) is another linear molecule, consisting of two O-C bonds that are 180 degrees apart. In SCl2, the sulfur is in group 6 or 16 in the periodic table and has six valence electrons. . The bond angle of CO2 is 180º and the hybridization of it is Sp. Therefore the molecular geometry is trigonal pyramidal. 2 ! Molecule # of valence e-Lewis Structure NO 3-5 + 3(6) + 1 = 24e- The Valence Shell Electron Pair Repulsion Theory (VSEPR) states the electron pairs surrounding an atom tend to repel each other and the shape of the molecule is the result of this electron pair repulsion. e.g. Bromine pentafluoride is polar because it is asymmetrical and has a lone pair. Hence the bond angle is maximum i.e. 26-6= 20e-= 10 lone pairs. C) 2+ D) Ca2+ E) Ca . Describe the molecular geometry. Identify the type of hybridization exhibited by sulfur.

As scientists we can predict a lot about how molecules react chemically and their physical properties by looking at Lewis structures and molecular geometry. All four compounds should have bond angles of $90^\circ$ if there were no other effects present.. For both nitrogen compounds, the effects are the short $\ce{N-X}$ bonds which lead to steric clash of the three substituents. The H-C-H bond angle in methane is _____.
