Which of the following order is CORRECT with respect to rate of hydrolysis?

Question

TestHub · Accepted Answer

The rate of hydrolysis depends on the availability of vacant d-orbitals and the polarity of the bond.

A. $S n M e_{4}$ is less polar than $S n C l_{4}$ , so $S n M e_{4} < S n C l_{4}$ .

B. $S F_{6}$ is sterically hindered and less reactive than $S F_{4}$ , so $S F_{6} < S F_{4}$ .

C. $PC l_{3}$ has vacant d-orbitals for water to attack, while $CC l_{4}$ does not, making $PC l_{3} > CC l_{4}$ .

D. $S n C l_{2}$ has a lower oxidation state and is less electrophilic than $S n C l_{4}$ , so $S n C l_{2} < S n C l_{4}$ .

Therefore, option C is correct.
