The fluorine is more electronegative than sulfur ie; fluorine attracts the bonded electron pair slightly more towards itself and gains partial negative charge and sulfur atom gains partial positive charge. "In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multipole moment. The three-dimensional arrangement of the fragment or atoms which create a molecule by getting together is known as Molecular Geometry. It regulates many properties like; There are several types of Molecular structure like; linear, bent, tetrahedral, octahedral, trigonal planar, trigonal pyramidal, etc. The electronegativity of atoms in these molecules is unequal due to which atoms have an unequal influence on the bonded electron pair. Therefore, the polarity of a molecule is directly proportional to the difference between their electronegativity and vice versa. In this structure, Sulfur is the least electronegative element and so transfers in the middle of the structure, and the diagram gives a three-dimensional structural information. Greater the electronegativity of an atom, the more it attracts the electrons to its side. SF4 covers under ‘Trigonal Bipyramidal’ because of its electron arrangements. The value of the dipole moment of SF4 is 0.632 D. Electronegativity: the term electronegativity of an atom is its strength to attract the bonded pair of electron.
