meaning of arrangement of molecules

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..

Carbon atom has four electrons in its outermost shell and hydrogen atoms have only one electron in its outermost shell. Carbon share one of its electrons with hydrogen to form a single bond each. Each carbon then requires three more electrons to acquire a stable configuration of the nearest noble..

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..

Five bond pairs orient themselves around the central atom in a trigonal bipyramidal way. A molecule having five bond pairs around its central atom has a triangular bipyramidal shape. Three bond pairs are arranged in an equatorial triangular plane and are oriented at an angle of..

This means that two hydrogen atoms are bonded together by a covalent bond. The bond dissociation energy of hydrogen molecule has been found to be 458 kJ mol - 1 and bond length equal to 74 pm. Moreover, since no unpaired electron is present in hydrogen molecule, it is ..

According to the assumptions of kinetic theory of gases, the free path traveled between two successive collisions will be a straight line with constant velocity. This means the path of a single gas molecule consists of a series of short zigzag path of different lengths. The ..

We are now in a position to write the rms speed of the molecules in terms of the absolute temperatur..

We are now in a position to write the rms speed of the molecules in terms of the absolute temperature. From equation (vi), And from equation (x), From these two, This can also be written a..

The middle number, when the numbers of a data set are arranged in order, is called ________. => range or Mode or mean or median..

According to this theory, the reactant molecules must come together to form an arrangement of atoms/molecules that facilitates the formation of products. This arrangement of the reacting species is called the transition stat..
