Among noble gases (from He to Xe ) only ...

Among noble gases (from He to Xe ) only xenon reacts with fluorine to form stable fluorides because xenon :

A

(1) has the largest size.

B

(2) has the lowest ionization enthalpy.

C

(3) has the highest heat of vaporization.

D

(4) Is the most readily available noble gas.

Text Solution

Verified by Experts

The correct Answer is:
B
Out of He, Ne, Ar , Kr and Xe, Xe has the lowest ionisation energy as ionisation energies decreases down a group.

Xenon reacts with Pt+F_6 to form

Among the noble gases only xenon is well known to form chemical compounds.

Give reasons which prompted Bartlett to react xenon with fluorine to form first noble gas compound.

Why do noble gases form compounds with fluorine and oxygen only.

Noble gases do not react with other elements because

Xenon has closed shell configuration but is known to give compounds with fluorine because

The noble gases have closed-shell electronic configuration and are monoatomic gases under normal conditions. The low boiling points of the lighter noble gases are due to weak dispersion forces between the atoms and the absence of other Interatomic Interactions. The direct reaction of xenon with fluorine leads to a series of compounds with oxidation numbers +2,+4 and +6. XeF_4 reacts violently with water to give XeO_3 The compound of xenon exhibit rich stereochemistry and their geometries can be deduced considering the total number of electron pairs in the valence shell. Argon is used In arc welding because of its:

S_(1): Argon is used in arc welding of metals or alloys to provide an inert atomosphere. S_(2):" XeF_(2),XeF_(4) and XeF_(6) are colourless crystalline solids and sublime readily at 298K . S_(3):XeF_(2),XeF_(4) and XeF_(6) are readily hydrolysed. S_(4): Xenon fluorides react with flourine ion acceptor to form cationic species and fluoride ion donors to form fluoro anions.

Give reasons : (i)Xenon does not form fluorides such as XeF_(3) and XeF_(5) .(ii)Out of noble gases, only xenon is known to form established chemicals compounds.

Among noble gases,gas of highest density is a) He b)Kr c)Xe d)Rn
