Question

question 7
the chemical formula for nitrosyl fluoride is nof. in the lewis structure, n is the central atom.
how many single bonds are in nof?
2
1
4
3

Explanation:

Step1: Calculate total valence electrons

Valence electrons: N=5, O=6, F=7. Total = $5+6+7=18$

Step2: Build Lewis structure framework

Central N bonds to O and F. To satisfy octets: N forms a double bond with O, and a single bond with F.

Step3: Count single bonds

Only the N-F bond is a single bond.
