L31 : Simple oxides - P Block Elements, Chemistry, Class 12 Video Lecture

hello friends this video on P block
elements part 31 is brought you by exam
fear calm no more for you from exam nah
let's understand some other important
compounds of oxygen family that is my
simple oxides so what are oxides C minor
II compounds of oxygen with elements are
called oxides again dioxide your
trioxide also any sample NGO is one
example of outside your box in with any
other element so one will even naturally
waveform more than one take of oxide we
talked about let's suppose iron so I
don't forms every home I don't also form
that we to put different types of oxide
form a heron if you talk about carbon so
oxide is nothing but my oxygen and some
other element you can have different
think of oxide okay if I boast of the
elements form ax oxide exception is
platinum gold and some noble gas so most
of the elements form oxide with a metal
nonmetal they form oxide and oxygen is
thus very abundant in nature okay and we
have different kind of oxide we have
simple oxides we have mixed oxides so I
can give oxide again classify into to
type knock side there is the mixed oxide
simple oxide they contain only one
chemical element and oxygen one chemical
element plus example you can have three
so you see the element is higher
aluminium here hydrogen here right
magnesium here so these are amino do so
here we have oxygen and
one more element they are simple to
still touch we talk about the mixed
oxides they have more than one one plus
chemical element and they have also not
so for example Fe tau 3 so it has fe
intense tightening its really sr t io 3
right or y3 el5 not that when they're
little rare idea it has Assad is a TI it
has why is there so this kind of oxide
are called mixed oxide we can also
classify these oxides based on their
acidic nature this was based on the
chemical element this is we can also
classify them as acetic oxide or basic
oxide or it can be amphoteric oxide or
it can be neutral on site sorry so we
talked about the acetic oxide these
oxides react with water to form acetic
oxide for example s becomes idling in CS
so2 when reacts with water to form h2s
for things almost acid sulfuric acid an
example of acidic oxide can be CL 2 O 7
carbon dioxide all these are - agassi
you know these react with water to form
that's it typically my non metal oxides
are typically not not always but
typically made non metal oxide it's
elastic oxide some metal with the higher
oxidation state they also have the SD
characteristic particularly my normative
example
we are sulfur chlorine come to believe
my nonmetals they form as Nagase but as
I told some metals with higher oxidation
state for example I went to seven CRO
seven we do I these is also a Gaussian
metals with higher oscillations when we
talk about the basic oxide the basic
oxide the oxide which give base with
water this is as big oxide leaves acid
gives acid with water basic oxide
this gives base with what these are will
be typically metal oxide example and in
two helsing oxide so these will be based
example calcium oxide yeah with water
you give you what calcium hydroxide this
is base so metallic oxides are nitric
oxides not all because some of the
metalic oxides are my acid a most of the
nitric oxides are mine basically okay
the third is amphoteric oxide see some
metallic oxides will exhibit the dual
nature
so let me write here yeah they will
happen it will behavior they also both
acid again busy behaving so then react
with both acid and alkali a good example
is al2o3 if you take here 203 you react
with let's say acid HCL me some water
also what you get is ill h2o 6 3 plus
and some reliance the same way n 2o 3
in react with some ways a good base can
be sodium hydroxide very popular base
some water right here also you get any
3o h6 you see this oxide reacts with
both acid and base these are my
amphoteric oxide the next is the neutral
oxide neutral oxide they are neither
acid normies they are due to example
carbon monoxide monoxide and these are
my neutral okay so oxide any classify as
simple and mix or we can also classify
oxides as the base again but again no
