WebbIn molecules with more than one bond, both shape and bond polarity determine whether or not the molecule is polar. A molecule must contain polar bonds in order for the molecule to be polar, but if the polar bonds are aligned exactly opposite to each other, or if they are sufficiently symmetric, the bond polarities cancel out, making the molecule nonpolar. WebbThe Shape of Molecules. The three dimensional shape or configuration of a molecule is an important characteristic. This shape is dependent on the preferred spatial orientation of covalent bonds to atoms having two or more bonding partners. Three dimensional configurations are best viewed with the aid of models. easy chicken vindaloo recipe

The electrons and the nuclei settle into positions that minimize repulsion and maximize attraction. Thus, the molecule’s shape reflects its equilibrium state in which it has the lowest possible energy in the system. Why do compounds form different shapes?

WebbThe shape of a molecule can be predicted based on the number and arrangement of electron pairs around a central atom. The geometry is determined by minimizing the repulsions between electron pairs in the bonds between atoms and/or lone pairs of electrons as postulated by VSEPR theory. How do valence electrons influence shape? WebbA molecule whose central atom contains only two electron groups orients those two groups as far apart from each other as possible — 180° apart. When the two electron groups are 180° apart, the atoms attached to those electron groups are also 180° apart, so the overall molecular shape is linear. Examples include BeH 2 and CO 2:
