MCQ
Which of the following statements is correct
  • A
    $S{F_4}$ is polar and non-reactive
  • B
    $S{F_6}$ is non-polar and very reactive
  • C
    $S{F_6}$ is a strong fluorinating agent
  • D
    $S{F_4}$ is prepared by fluorinating $SC{l_2}$ with $NaF$

Answer

$SF _6$ is good florianating reagent. $SF _6$ is chemically inert due to the reason that the six $F$ atoms protect the sulphur atom from attack by the reagents to such an extent that even thermodynamically most favorable reactions like hydrolysis do not occur, that is non reactive. $SF _6$ is non polar.
