Final answer:
The electron pair for n in NO2Cl is represented as Ö=N—Cl.
Step-by-step explanation:
In the molecule NO2Cl, the electron pair for nitrogen (n) is represented as a lone pair of electrons on a terminal atom. We can choose to use a lone pair from either oxygen (O) or chlorine (Cl). Since O forms a double bond more frequently than Cl, it is reasonable to select a lone pair from oxygen. Therefore, the electron pair for n in NO2Cl is represented as:
Ö=N—Cl:
