Question
Which of the following halides cannot be hydrolysed at room temperature?<br>(I) TeF6<br>(II) SF6<br>(III) NCl3<br>(IV) NF3<br>Choose the correct code:
Answer: D
💡 Solution & Explanation
In SF6, S is sterically hindered by six fluorine atoms hence, attack of H2O molecule will not occur. NF3 is not hydrolysed due to absence of vacant orbital either on N or F atom. TeF6 is hydrolysed due to large size of Te.
