JEE Main levelSingle correct optionDifficulty 2 of 3ph064

Chlorine trifluoride and bromine trifluoride are used in the processing of nuclear fuel because they convert uranium into

A $UO X_{2} F X_{2}$
B $UCl X_{4}$
C $UF X_{6}$
D $UF X_{4}$

Answer: C

These powerful fluorinating agents oxidise uranium to the volatile hexafluoride, e.g.

U + 3 ClF X_{3} UF X_{6} + 3 ClF

. Volatile

UF X_{6}

is used for isotope separation.
