Xenon - Oxygen Compounds Video Lecture - NEET

hello friends this video on p-block part
60 is brought you by exam viacom no more
fear from exam let's talk about the
xenon and oxygen come form in fact we
have just seen that hydrolysis of XE
xenon tetrafluoride into it except oh
right with water gives xeo3 that is
xenon trioxide let me show you the
reaction xenon tetrafluoride
and these reactors are important because
if you're getting this
they don't trioxide so you get a check
and it's an oxide molecule we can
balance this reaction this is 12 this
will be 4 this will be 2 24 and 3 okay
if we talk about this reaction is it on
hexafluoride and you do hydrolysis with
water you get again non-drive side and
HR ok and again you talk about more
oxygen are bound we have seen that the
partial hydrolysis of X ef6 we do a
partial hydrolysis of X cf6
we just saw this reaction you get XE
where for once and if you do the partial
hydrolyze this with little bit of more
water but more water you get X 0 - ok
these are oxy provides xenon oxychloride
a non dioxide and please note this xeo3
which i have just discussed these guys
there is colourless and exclusive solid
colorless but it is explosive
okay this explosive talk about the
structure of this xq 3 this is a non 1 2
3 4 5 6 7 8
oxygen to 1/2 oxygen yeah so I have
three bonds and one lone pair that is
one lone pair plus 3 1 where the shape
will be pyramidal ok so if you talked
about more properties of this is a non
non trioxide it is again as I told
colorless non-volatile solid it is
soluble in water it is soluble in water
and is a very strong oxidizing agent the
reaction is because I will xeo3
in acid maybe i'm it is a very strong
oxidizing agent
it comes and on and you see it is
getting reduced on its own right from
plus six to zero that means it is a
strong oxidizing h okay so if you talk
about x0f for this particular thing it
is my colorless and volatile liquid this
is the liquid I talk about the shape of
XE o f4 will have a xenon one two three
four five six seven eight one oxygen
will take two points on chlorine to
fluorine three fluorine and and this is
my own pain so I have one lone pair plus
one two three four five one bit okay so
with this I have a square pyramidal
structure
so for this I have a square pyramidal
structure ex-ceo Airport okay now let's
take some uses of this noble gas and the
issues include to talk about the helium
helium is a very light gas it is not
inflammable so it is used in balloons
here helium is used it is lighter and it
is not improbable okay and it is also
used in nuclear reactor helium we have
seen the reaction of helium in the
nuclear reactor it is also used for
helium is also used for kryos and
division where you take how caring the
experiment with a very low temperature
okay so it is also used he M is also
used for MRI my magnetic resource
imagining that is used for medical
industry in the medical industry to see
your brain or different parts of the
body to diagnose a disease nicely helium
is also used as my saw solvent actually
a USA solvent it is used as diluent
where for oxygen in the modern diving
apparatus because why it is low it has
very low solubility in blood we'll talk
more about this in the next slide
since the it has low solubility in the
blood helium is used here also he lives
here okay we talked about the neon it is
used for fluorescent lights argon since
it is inert it is used in electric bulb
argon in fact xenon and Krypton also
mark passing if in use but they are used
in the bulbs and the lamps okay the
Ragan is again a radioactive radioactive
element so it is using the nuclear
science
it is actually used for treating cancer
rather than is used to treat cancer okay
let's take this numerical actually which
talks about widely used in the diving
apparatus I just explained that we'll
discuss in the next slide see actually
the helium is used in this diving
apparatus one is because it is medium
low solubility in the blood but is that
the reason big deal
C+ helium is non-toxic why because it is
here okay
now if you talk to the scuba divers when
they go at a height depth the pressure
is very high at this point pressure is
high okay now if you talk about the
normally a normal air has 75% nitrogen
okay and oxygen no I
if the scuba diver breathes normally
let's suppose this has normally if it
has normal layer it will have 75 percent
nitrogen also in this now at a high
pressure at the lower depth or at a
great definitely the pressure is high
the solubility increased solubility of
gas we have seen that solubility Oh gas
a liquid increase with pressure increase
the pressure the more is the solubility
of gas and liquid is something we have
seen in the previous chapter we won't
know this constant please watch my
previous videos where we explain this
now after such a great depth the
pressure is very high and us the
solubility of gas that is nitrogen here
in the liquid that is blood here right
increase okay so when the scuba divers
moves down if it is normal nitrogen
normal light which is solubility in the
guy in the
increase so more and more nitrogen will
get dissolved in this plug but when the
scuba diver comes back again these
nitrogen will come out as bubble why
because immediately immediately you are
changing the pressure the moment is on
the scuba diver comes back here we have
low pressure again what will happen the
solubility of nitrogen in the blood when
degrees and this nitrogen will come out
as bubble and this is dangerous
to help this forms a condition called
veins and this condition is a medical
condition it can take life also it is
very threatening it's life threatening
so nitrogen can be used okay so one
option is you use pure oxygen but our
body is not used to clear oxygen so if
you use pure oxygen it is again harmful
for the human body so something has to
be mixed with oxygen so we need
something which is non-toxic and also
something which is not much Solomon in
the blood because if it is soluble in
the blood again the same thing will
happen see nitrogen is not toxic but the
problem is nitrogen is nitrogen is
soluble in the blood high-pressure
nitrogen is more soluble in the blood
Newton is more solvent in the blood
actually if you go down the nitrogen is
more Solomon in the blood is black his
nitrogen is already the blood and with
this what happens is when again this
whatever comes up these nitrogen comes
out this bubble and there is a medical
condition called bends that is
life-threatening so we need something
which is non-toxic and not much soluble
in the blood and helium is a good
substitute helium is not toxic any
helium is also not soluble not highly
soluble to the blood okay
