arrangement of molecules

Nature of Matter..

In polyatomic molecules the dipole moment not only depends upon the individual dipole moments of the bonds but also on the spatial arrangement of the various bonds in the molecule. In such molecules the dipole moment of the molecule is the vector s..

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..

> molecule, the bond pairs are pushed slightly inwards due to greater lone pair- bond pair repulsions. Thus, the ideal bond angle of 10928' for a tetrahedral arrangement in such molecules is lower, the actual HPH angle, being 104 o . Thus, PH 3 is a trigonal pyramidal ..

The molecules of a gas are far apart. The inter-molecular force of attraction is negligible and they have no fixed freedom of motion. Hence gases have neither fixed shape nor volume. They completely occupy the container and take the shape and the volume of the container. Molecular st..

The molecules in a solid are very closely packed. The inter-molecular force of attraction is very strong in solids. Hence solids have a definite size and shape. Molecules of a solid vibrate about their mean position. Molecular structure of a solid Solids cannot be compresse..

Hydrocarbons - Isomerism in Alkanes - Isomers are compounds having the same molecular formula but different properties due to different structural arrangement of atoms in their molecules..

Solids are substances having definite volume and definite shape. In terms of kinetic molecular model, in solids there is a regular order in the arrangement of the constituting particles (atoms, molecules or ions) i.e. the particles constituting the solids occupy fixed positions ..
