Question

follow each step to complete the name of the covalent compound below:

1. use prefixes to indicate the number of atoms of each element.

exception: never use the \mono\ prefix on the first element.
greek prefixes
mono → 1
di → 2
tri → 3
tetra → 4
penta → 5
hexa → 6
hepta → 7
octa → 8
nona → 9
deca → 10
nbr₂
nitrogen? bromide

Explanation:

Step1: Identify the number of Br atoms

In the formula \( \text{NBr}_2 \), the subscript of Br is 2.

Step2: Find the corresponding prefix

From the Greek Prefixes table, the prefix for 2 is "Di".

Step3: Apply the prefix to Br

Since Br is the second element, we use the prefix "Di" for the number of Br atoms.

Answer:

Di
