Question

${ClF}_3$ is a............ in the reaction
$CI{F}_3+As{F}_3⟶\left[Cl{F}_2{]}^{+}\right[As{F}_4{]}^{-}$
and is a ................ in the reaction
$Cl{F}_3+NOF...\to \left[NO{]}^{+}\right[Cl{F}_4{]}^{-}$

• A. Lewis base, Lewis base
• B. Lewis acid, Lewis acid
• C. Lewis acid, Lewis base
• D. Lewis base, Lewis acid

Answer 1

Answer: (D)

Lewis base, Lewis acid

${ClF}_3$ is a lewis base in the reaction as it is donating charge pair (fluoride ion).
$CI{F}_3+As{F}_3⟶\left[Cl{F}_2{]}^{+}\right[As{F}_4{]}^{-}$
and is a lewis acid in the reaction as here it is accepting electron pair from NOF.
$Cl{F}_3+NOF\to \left[NO{]}^{+}\right[Cl{F}_4{]}^{-}$
