PS: I've tried drawing the structure for you but Yahoo answer won't draw it! But isn't the bond angle supposed to be smaller than 180 degree due to the lone pair-lone pair repulsion? A) The bond angles in SF5+ are expected to be A) 90°. XeF 2 was considered to be a possible convenient replacement for elemental fluorine especially in addition reactions to a double bond. Furthermore, the angles are not exactly 120 degrees as in the case of a trigonal planar molecule where the surrounding atoms are all the same. Answer Save. These valence electrons repel each other and by having 3 pairs of electrons, bonding pairs are forced to be as far apart as possible, forming a 180 degree bond angle. AX 2 E 2 Molecules: H 2 O. > You must draw the Lewis structure of "XeF"_5^+. See the answer. 2 Answers. It has 2 bond pairs and 3 lone pairs, so it has a linear shape. Part C. What is the value of the bond angles in BF3? In these cases, the electron-domain geometry is always trigonal bipyramidal. The ClF2- molecule has a single bond between each Florine. As I have described earlier, the two lone pairs of electron of SF2 gives it a bent shape. The most favourable arrangement is distorted tetrahedral i.e. According to VSEPR theory, if there are three electron domains in the valence shell of an atom, they will be arranged in a(n) _____ geometry. In this, nitrogen atom lies at the centre and three hydrogen atoms occupying the triangular base and the orbital with a lone pair of electrons from the apex of the pyramid. The bond angles in SCl2 are expected to be A) a little less than 109.5°. Part D. What is the value of the bond angle in XeF2? Thirty are in lone pairs with F atoms. pyramidal. This leads to decrease in H – N – H bond angles from a normal angle of a tetrahedron (109.5°) to 107°. When energy is given, one electron from one of the three filled 5p orbital is excited (enters 5d orbital); under goes hybridization and forms two Xe-F bonds to give XeF2.
