WebbIt doesn't matter about any similarity or not between the right hand side and the left hand side. The two forms are known as "cis" and "trans" isomers. They are also known as "Z" and "E" isomers. Geometric isomerism is a specific form of stereoisomerism. This form of isomerism arises because there is no rotation about the double bond. WebbThe Shapes of Molecules Different molecules have different shapes. The shape of a molecule is dictated by the arrangement of Electron Pairs. This is because Electron Pairs repel each other. The molecule settles in a state where the Electron Pairs are furthest apart from each other. Different types of Electron Pairs have different repulsions. dicks yahoo financeWebbOrbitals Chemistry (s, p, d, and f Orbital) - Atomic Orbitals are of four different kinds, denoted s, p, d, and f, each with a different shape.

WebbAnswer 1: Phosphorus is in group 15, so has 5 valence electrons; Cl is in group 17, so has 17 valence electrons All 5 electrons are used to form covalent bonds with Cl and there are no lone pairs This gives a trigonal (or triangular) bipyramidal shape: Phosphorus pentachloride or phosphorus (V) chloride Answer 2: WebbMolecule Shapes The shape of a molecule can be determined by considering the type and quantity of electron pairs : 1. Find the number of electron pairs. 2. Determine how many of the pairs are bonding pairs and how many are lone pairs. 3. Bonding pairs indicate the basic shape and lone pairs indicate any additional repulsion.
