Electron: trigonal bipyramidal Molecular: sawhorse. Methane (CH4) and the perchlorate ion (ClO4−) are both described as tetrahedral. This is because of two groups of bonding electrons and two lone pairs of electrons. Which compound has a longer $\mathrm{C}-\mathrm{Cl}$ bond? Start here or give us a call: (312) 646-6365, © 2005 - 2021 Wyzant, Inc. - All Rights Reserved, a Question ion is tetrahedral shape and has 4 bond pairs and no lone pair of electrons, and bond angle is 109.5, SN1SN2 - Nucleophilic Substitution Reactions, The Seven Steps of Goal Setting - Zig Ziglar Remix, Science Study Tip - Especially for Organic Chemistry. 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. clo4 bond angle. Which species has the smaller bond angle, ClO4 - or ClO3 -? The degree of this type of repulsion depends on the electronegativity of the atoms. Lets look at AsF4- Lewis structure.
