shapes of molecule

The shape of a molecule affects its chemical and physical properties. For instance, some of the unique properties of water are due to the angular shape of its molecule (H 2 O). The stability and the self-replicating property of DNA is due to its double-..

Methane is the simplest carbon. Here, the four half filled orbitals belonging to the valence shell of carbon atom undergoes hybridization, resulting in the formation of four sp 3 hybrid orbitals which are directed towards the corners of tetrahedron. Each of the sp 3 hybrid orbitals of carbo..

Hybrid Orbitals and Molecular Shapes of Molecules Involving d Orbitals - The Hybridization and molecular shapes of some molecules involving d-orbitals are summarized in the table given belo..

To use this theory for predicting the shapes of molecules, the number of electron pairs (both, shared and lone pairs) is simply counted. This is illustrated by taking a typical molecule of the type AB n . 'A' is the central atom, 'B' atoms are bonded to 'A' by single ..

The Hybridization and molecular shapes of some molecules involving d-orbitals are summarized in the table given belo..

In a molecule having two bond pairs of electrons around its central atom, the bond pairs are located on the opposite sides (at an angle of 180 o ) so that the repulsion between them is minimum. Such molecules are therefore linear. Some molecules, which show linear geo..

The molecular structure of interhalogen compounds can be explained on the basis of VSEPR theory. The structures of a few interhalogens are shown in figure. Structure of interhalogen compounds It may be noted than in general, the central halogen atom assumes: a) sp 3 d hybridization in..

Molecule having four bond pairs of electrons around the central atom, arrange their electrons tetrahedrally. These molecules have tetrahedral shapes and the four bond pairs are at an angle of 10928' with respect to each other. Some molecules which show tetra..

In a molecule having three bond pairs of electrons around its central atom, the electron pairs form an equilateral triangular arrangement around the central atom. These molecules have trigonal planar (or triangularplanar) shape and the three bond pairs are at 120C wit..

Gases do not posses any definite shape or volume. They will completely fill all the space available to them. The tendency of a gas to fill the available volume within a container is the result of the freedom that gas particles have to move everywhere in the available space. This freedom ..
