Draw Lewis dot structure (CH3)4 NCL A SALT
Lewis Dot Structure is used to represent how atoms are attatched to each other (bonded) in a molecule, i.e., which atom is bonded to which one in the molecular structure. Also, it shows the lone pair of electrons (valence electrons which do not participate in chemical bonding) of the atoms in the molecule.
Lewis structure is especially useful in finding out which atom in the atom has lone pair of electrons attatched to it.
(CH3)4NCl, i.e., Tetramethylammonium Chloride, is an ammonium salt with the methyl groups attatched to the nitrogen atom tetrahedrally making it a quarternary ammonium salt. The Nitrogen atom has 7 electrons in total, with 5 valence electrons with can actively participate in chemical bonding. 4 of these valence electrons form covalent bonds with the 4 Methyl Groups, i.e., (CH3) and 1 valence electron forms an ionic bond with the Chlorine electron. Chlorine has 7 valence electrons of which 3 are lone pairs while 1 is an unpaired electron. This 1 unpaired electron of Chlorin pairs with the 1 unpaired electron of Nitrogen.
The Lewis dot structure of this Salt is shown in the Figure.
