Phosphorus oxychloride has the chemical formula POCl3, with P as the central atom. In order to minimize formal charge, how many
Elina [12.6K]

Answer:

Phosphorus makes 5 bonds with other atoms

Explanation:

POCl_{3} has total 32 number of valence electrons (P has 5 , O has 6 and Cl has 7 valence electrons).

These valence electrons are used to draw Lewis structure of POCl_{3}.

Formal charge on an atom = (no. of valence electrons of the atom)-(no. of covalent bonds attached to the atom)-(no. of electrons in lone pair of the atom)

Applying octet rule (atoms have eight electrons in their valence shell) and minimizing formal charge of POCl_{3}, it has been found that P makes total 5 bonds with rest of the atoms.

Lewis structure of POCl_{3} along with formal charge (in parentheses) has been given below.
