Which statement about noble gases is not correct?
- A 'Xe' forms \(\mathrm{XeF}_6\) under suitable conditions
- B 'Ar' is used in electric bulbs
- C The number of lone pair of electrons present on \(\mathrm{Xe}\) in \(\mathrm{XeF}_2\) is 3.
- D 'He' has the highest boiling point among all the noble gases
Answer & Solution
Correct Answer
(D) 'He' has the highest boiling point among all the noble gases
Step-by-step Solution
Detailed explanation
(d) (a) \(\mathrm{Xe}+3 \mathrm{~F}_2 \stackrel{\Delta}{\longrightarrow} \mathrm{XeF}_6\) (b) Ar used in electric bulbs. (c) 3 lone pairs are present in \(\mathrm{XeF}_2\). \(\left(s p^3 d\right)\) Linear (a), (b), (c) statements are correct but statements (d) is incorrect. (d)…
