Why SF6is innert towards hydrolysis

Posted by Akshya Pandey 7 years, 11 months ago

CBSE > Class 12 > Chemistry

5 answers

Asim Khan 7 years, 11 months ago

In SF6 there are no vacant d-orbitals as the S is bonded with 6F atoms hence completing the octet of sulphur. Also S is surrounded by six F- ions octaherally hindering the incoming water molecule to attack S atom. By which SF6 remains chemically inert towards hydrolysis reactions. Hope it helps!!! Best wishes...
