suppose that AB3E, a hypothetical molecule is discovered, Predict wether the molecule is polar or non polar
Answer (1)
AB₃E is a polar molecule because of its asymmetrical shape caused by the lone pair on the central atom, resulting in a net dipole moment.To predict whether the hypothetical molecule AB₃E is polar or nonpolar, we can use VSEPR (Valence Shell Electron Pair Repulsion) theory.A = central atomB₃ = three bonded atomsE = one lone pair on the central atomStep-by-StepThe molecular shape of AB₃E is trigonal pyramidal (like ammonia, NH₃), due to three bonding pairs and one lone pair.In this shape, the lone pair pushes the bonding pairs down, creating an asymmetrical shape.Since it's asymmetrical, the dipole moments do not cancel out.
