does NOCL follow the octet rule

yes.

To determine if NOCl (Nitrosyl chloride) follows the octet rule, we need to examine the valence electrons of each atom in the molecule.

The central atom in NOCl is nitrogen (N), which is connected to an oxygen (O) atom and a chlorine (Cl) atom. Nitrogen has 5 valence electrons, oxygen has 6 valence electrons, and chlorine has 7 valence electrons.

To determine the total number of valence electrons in NOCl, we add up the valence electrons of each atom: 5 (N) + 6 (O) + 7 (Cl) = 18 valence electrons.

Now, let's distribute these electrons to satisfy the octet rule, which states that atoms tend to gain, lose, or share electrons to achieve a stable electron configuration with 8 valence electrons.

Starting with the central atom, nitrogen (N), it needs 3 additional electrons to reach an octet. Since chlorine (Cl) is more electronegative than oxygen (O), we will place the remaining 15 electrons around nitrogen and chlorine, with chlorine getting more electron density.

The final electron distribution is:

Nitrogen (N): 8 electrons (2 from a lone pair and 6 from a double bond with oxygen)
Oxygen (O): 6 electrons (2 from a double bond with nitrogen and 4 in lone pairs)
Chlorine (Cl): 4 electrons (all in lone pairs)

By following this distribution, we can see that NOCl does not strictly follow the octet rule for all atoms. Nitrogen has 10 valence electrons instead of 8. However, this does not mean that the molecule is unstable or violates any chemical principles. It suggests that the octet rule is not always applicable to all elements and compounds.
