Carbon Family Video Lecture | Chemistry for JEE Main & Advanced

hello friends this video on PA payments
part 16 is brought to you by exam fear
calm no more fear from exam so let's
start with a group 14 you limit the
carbon family right so the carbon here
is the 72 most abundant crust we have
this carbon family there we talk about
carbon silicon germanium 10 LED all
these remains in power so carbon is
nothing but a very critical element and
you know that the special chapter in
chemistry for that special
characteristics and uses of carbon and
the carbon exists in three alert drops
at various forms actually it exists is
coal diamond graphite sometimes for
charcoal so they are there they are
various form but in elemental form it
exists is coal graphite evening and in
combined state it is present as the
metal components hydrocarbons they are
so many hydrocarbons in fact if you see
the already chemistry branch itself with
for this right to college soap is one
example of hydrocarbon right and also
you see the carbon dioxide there also we
have carbon so these are in the combined
state and in the elemental state exist
in these three months there's a toured
the whole organic chemistry is devoted
to carbon compound please don't organic
chemistry is Willie with the carbon and
hydrogen compounds if you see about
carbon dioxide carbon monoxide
these things we studying in organic
chemist even if it has cover so because
organic eventually will be the carbon
hydrogen and carbon concatenation
properties where it forms big big
structures it is essential for all the
living organism we have what amount of
carbon in a body is very critical for us
survive and also if you see in the
photosynthesis also carbon is used that
is also very critical plants use carbon
dioxide to produce food using
chlorophyll and naturally operating I
showed up there too one is C 2 L and C
13 they are the two naturally occurring
carbon compound or carbon forms and they
are stable there is one more that is
there which is not mashed which is very
very rare this third I to talk
c14 is unstable actually and this is
radioactive
this is radioactive and this is useful
radioactive carbon dating is used to
find what is the age of a particular
monument for example some monument is
formed to the earth and then they'll
find out what is the age of that or
let's my we found some tree we want to
find what is the age of the tree so
these things before using these hot
isotopic this C 14 this is helpful it's
very helpful actually because the our
collage Department if you want to find
the history of all this ancients they
want to find how old the stone is which
let's suppose someone has got some stone
somewhere by Danes in mind they want to
find how it is to stone it is or else
terms they can find using targeting
process this is this seaport in carbon
is silicon is also my part of carbon
family and if you see how the sand is
nothing but silicon and they are very
much doubled in their this second most
abundant in the earth trust 27.7% by
moss and the very important compounds to
create the ceramics cements glass glass
glass ceramic with cement very critical
to create this and silicon is also used
to create semiconductors they are used
silicon so very useful to create
semiconductors and this is something
which has driving the world now or this
IT industry computer science or the
computers fridge microwave washing
machine mobile phones all these runs on
chips they are all made of silicon
silicon is very powerful element
actually you can say that right so we'll
discuss more about silicon also
germanium would exist only in place and
when you talk about it exists mainly in
the cast right and Galena foam lead lead
was used earlier this pencil that's why
the it's called lead pencil but now
since the latest poisonous it is no
longer the lead is not on the views here
so here instead of let me use
graphite what is graphite is nothing but
you know let carbon is using pencils no
but still the lead pencil one holds a
deep red will also use earlier in petrol
for anti knocking thing but against
invalid is poisonous it is not over used
as I told the silicon right and gallium
these are used create transistors and
silicon deters ultra pure form of
silicon is used to be semiconductors
which are very very critical for us it
has given a new dimensions to a life as
given all the comforts we expected when
you're watching this video because you
are singing in front of a computer which
is nothing but we from silicon thank you
