But ClO 4-ion is tetrahedral shape and has 4 bond pairs and no lone pair of electrons, and bond angle is 109.5 o. Bond Angle. CH4 or ClO4 1-Triangular Pyramidal Shape. A quick explanation of the molecular geometry of ClO4 - (Perchlorate ion) including a description of the ClO4 - bond angles.Looking at the ClO4- Lewis structure we can see that there are four atoms attached to the central Chlorine (Cl). As a result they will be pushed apart giving the ClO4- molecule a tetrahedral molecular geometry or shape. AB3E (4 domains - 3 bonding 1 nonbonding) Chlorine in Group 7/17. ... Due to the presence of a lone pair, there will be a deviation in bond angle for $\mathrm{ClO}_{3}^{-} .$ This is because repulsions between lone pair and bond pair are more than between bond pairs. You’ll look at the number of chemical bonds and then the number of nonbonding electron pairs Switch to. Get the detailed answer: (a) Methane (CH4) and the perchlorate ion (ClO4–) are both described as tetrahedral. But it is 107 degrees because the bonding pair occupies less space than the nonbonding pair. Your dashboard and recommendations. Lets consider the Lewis structure for CCl 4. Answer format: "geometry, x" without quotes where x is the possible bond angles with "and" as a connector where necessary and less than and greater than are in words. Personalized courses, with or without credits. You can also find the three-dimensional shape in thiazyl trifluoride, NSF3, and ions of phosphate (PO43-), sulfate (SO42-), and perchlorate (ClO4-). Linear Shape. The 3D shape of a molecule has a lot to do with how the molecule behaves. Which species has the smaller bond angle, ClO4 - or ClO3 -? In essence, ionic bonding is nondirectional, whereas covalent bonding is directional. ClO4− will have the smaller bond angle since it has more electron groups with a total of four electron groups, and more electrons groups will require smaller bond angles to fit around the central atom. It is close to the tetrahedral angle which is 109.5 degrees. Explain.

Chemical bonding - Chemical bonding - Molecular shapes and VSEPR theory: There is a sharp distinction between ionic and covalent bonds when the geometric arrangements of atoms in compounds are considered. This shape consists of a triangle with two electron pairs directly above and below it. tetrahedral, 1090281 . SOLUTION: (a) For PF3 - there are 26 valence electrons, 1 nonbonding pair PF F F The shape is based upon the tetrahedral arrangement. I thought the lone pair would push the other atoms closer together and result in a slightly smaller bond angle. For number 71 in the homework for chapter three, the structures for TeF4 and SbCl4- are both see saws but the book says the angles are greater than 120 and 90. Next would be the oxygen of the OH group connected to the carbon which would have a bent shape with bond angles of <109.5 (because it has two bonds but two lone pairs).
