someone can check my answer for me? and b) Shape and Bond Angle answer would be great too! :)
a) NF3 Structure = 26 electrons, Shape = trigonal pyramidal, Bond Angle = 105.5.
b) TeCI2 Structure = 30 electrons, Shape = ? Bond Angle = ?
c) CCI4 Structure = 32 electrons, Shape = Tetruaheral, Bond Angle = 109.5.
d) SO2 structure = 18 electrons, Shape = bent bond Angle = 120 (119).
a, c. and d are correct. H2Te is angular; there is no reason to believe TeCl2 would be different but I could not confirm that similarity.
Sure, let's go through each answer and check them.
a) For NF3, you correctly calculated the number of electrons, which is 26. To determine the shape, we can use the VSEPR theory. Nitrogen is the central atom, and it has three bonded fluorine atoms and one lone pair of electrons. This gives us a trigonal pyramidal shape. The bond angle is determined by the electron arrangement around the central atom. In this case, it is approximately 105.5 degrees.
b) For TeCI2, you correctly calculated the number of electrons, which is 30. To determine the shape, we can use the VSEPR theory again. Tellurium is the central atom, and it has two bonded chlorine atoms. Since there are no lone pairs, the shape would be linear. The bond angle, in this case, would be 180 degrees since it is a straight line.
c) For CCI4, you correctly calculated the number of electrons, which is 32. To determine the shape, we can use the VSEPR theory once more. Carbon is the central atom, and it has four bonded chlorine atoms. Since there are no lone pairs, the shape would be tetrahedral, with bond angles of approximately 109.5 degrees.
d) For SO2, you correctly calculated the number of electrons, which is 18. To determine the shape, we can again use the VSEPR theory. Sulfur is the central atom, and it has two bonded oxygen atoms. Additionally, it has one lone pair of electrons. This gives us a bent shape. The bond angle is approximately 120 degrees, but due to the presence of the lone pair, it is slightly reduced to around 119 degrees.
In summary:
a) NF3: Structure = 26 electrons, Shape = trigonal pyramidal, Bond Angle = 105.5 degrees.
b) TeCI2: Structure = 30 electrons, Shape = linear, Bond Angle = 180 degrees.
c) CCI4: Structure = 32 electrons, Shape = tetrahedral, Bond Angle = 109.5 degrees.
d) SO2: Structure = 18 electrons, Shape = bent, Bond Angle = 120 degrees (approximately 119 degrees).
