Correct Option - 4
Detailed Solution:Sometimes, when maximum covalency is obtained, the halides become inert to water, thus SF? (or similarly CCl? ) is stable. This is because SF? is coordinately saturated and sterically hindered. Thus, SF? is inert to water, because of kinetic rather than thermodynamic factor.
A. PCl? + 4H? O → H? PO? + 5HCl
B. SiCl? + 4H? O → Si (OH)? + 4HCl
C. BCl? + 3H? O → B (OH)? + 3HCl
