Question

provide the correct iupac name for pbr₃.

Explanation:

For naming binary covalent compounds (compounds formed between two non - metals like \(P\) (phosphorus) and \(Br\) (bromine) in \(PBr_3\)):

• The first element (\(P\)) is named as the element itself (phosphorus).
• The second element (\(Br\)) is named with the suffix “-ide” (bromide).
• We use prefixes to indicate the number of atoms. Since there are 3 \(Br\) atoms, the prefix “tri-” is used.

Answer:

Phosphorus tribromide
