The sinle quantum number by Neil.s Bohr and the appearance of several spectral lines in a particular series of Hspectrum, suggest that there more than one quantum to explain all the quantized properties of an electron in a particular energy level inside the atom. If fact when the properties of the electron is transformed from Cartesian co-ordinate to polar co-ordinates then it becomes the function of r, theta and phi suggesting three independet quantum numbers. In addition to this a fourth quantum number is required to consider the spinning behaviour of an electron. The principal quantum number n suggest the orbit number in which electron revolves, Azimuthal quantum number 1 suggest the shape of orbitals, magnetic quantum number m, gives orientation of orbital in presence of external magnetic field, while spin quantum number s, gives direction of an electron about its own axis n != 0 values of "1" ranges in between 0 to (n-1), while m depends upon 1. Total number values of m = 21+1, and "m" ranges in between -1 to +1 including 0. For each electron spin will be +-(1)/(2) Which of the following is not possible

Covalent molecules formed by heteroatoms bound to have some ionic character. The ionic character is due to shifting of the electron pair towards A or B in the molecule AB. Hence, atoms acquire small and equal charge but opposite in sign. Such a bond which has some ionic character is described as polar covalent bond. Polar covalent molecules can exhibit dipole moment. Dipole moment is equal to the product of charge separation, q and the bond length, d for the bond. The unit of dipole moment is Debye. One Debye is equal to 10^(-18) esu cm. Dipole moment is a vector quantity. It has both magnitude and direction. Hence, dipole moment of molecules depends upon the relative orientation of the bond dipoles, but not on the polarity of bonds alone. A symmetrical structure shows zero dipole moment. Thus, dipole moments help to predict the geometry of the molecules. Dipole moment values can be used to distinguish between cis-and traps-isomers, ortho-, meta-and para-forms of a substance, etc. The percentage of ionic character of a bond can be calculated by the application of the following formula : % " ionic character " = ("Experimental value of dipole moment ")/("Theoretical value of dipole moment ") xx 100 Which are non-polar molecules?
