storyline 1 exam
bcl₃ is the product of boron and chlorine atoms. what is the name of this product?
○ boron chloride
○ boron (iii) chloride
○ boron (3) chloride
○ boron trichloride

Explanation:

Boron trichloride is the correct name for BCl₃. In naming covalent compounds, prefixes are used to indicate the number of atoms of each element. The prefix "tri -" indicates three chlorine atoms. Boron chloride is too general as it doesn't specify the number of chlorine atoms. Boron (III) chloride is used for ionic compounds (indicating the charge of the metal ion, which is not relevant here as it's a covalent compound). Boron (3) chloride is an incorrect notation.

Answer:

boron trichloride
