Question

The first chemical compound of a noble gas prepared in the laboratory was ______. It was prepared by ______ in ______.

Answer 1

The first chemical compound of a noble gas prepared in the laboratory was XePtF₆. It was prepared by Neil Bartlett in 1962.

Explanation:

The chemistry of noble gases began in 1962 when Neil Bartlett discovered that platinum hexafluoride (PtF₆) could oxidise xenon, forming the first true noble gas compound, xenon hexafluoroplatinate (XePtF₆). This discovery proved that even noble gases can form chemical compounds under specific conditions.
