JEE Main levelOne or more correct optionsDifficulty 2 of 3bn099

Select all correct names for binary covalent compounds in the Greek-prefix system (mono- is omitted for the first element).

A $SF X_{6}$ - sulfur hexafluoride
B $N X_{2} O X_{3}$ - nitrogen trioxide
C $CO$ - monocarbon monoxide
D $PCl X_{3}$ - phosphorus trichloride

Answer: A, D

SF X_{6}

is sulfur hexafluoride and

PCl X_{3}

is phosphorus trichloride.

N X_{2} O X_{3}

needs the prefix di- on nitrogen (dinitrogen trioxide) because there are two N, and

CO

is carbon monoxide.
