L1 : Introduction - Hydrocarbons, Class 11 Video Lecture

hello friends this video on hydrocarbons
part 1 is brought you by exam Theodore
Hall no more fear from exam the
objective of this lesson is to name the
hydrocarbons according to the highways
in organization to write the structures
of isomers of alkanes alkenes alkynes
and aromatic hydrocarbon you learn about
the proliferation of various
hydrocarbons
you try to distribute between alkanes
alkenes alkynes metric hydrocarbons
based on their physical and key the
properties we also understand the
chemical reactions of alkane and
kinematic hydrocarbons so these are the
main ones we have so we'll understand
the chemical reactions of alkanes
alkenes alkynes in aromatic hydrocarbons
you'll understand or appreciate the role
of hydrocarbons a source of energy you
comprehend destruction of benzene
benzene understands a term ever ever by
density and we understand the mechanism
of electrophilic substitution reaction
on benzene will predict the directive
influence of the substituent's and we'll
learn about carcinogenicity and toxicity
it starts with the term high pecan
charcoal is all about hydrocarbon so
what are hyper bonds so as the name
suggests hydrocarbon hydro plus carbon
right so hydro is hydrogen carbon is
carbon so compounds of carbon that has
hydrogen they are called echo cards next
question is why should we study how to
call them right the definition of
hydrocarbon is good but the question is
why should we still be five carbon so if
you see hydrocarbon has no application
in our day-to-day life Rize will control
all the chaos ins whatever few will be
used right that is all hydrocarbon the
medicines we use most of them are
hydrocarbons the dye that is used to
color textiles all hydrocarbon the LPG
cylinder which we use in our home
on hydro try the kerosene lamp the the
kerosene fuel hell is hydrocarbon the
bottles we use most of the plastic items
we see around the toy the bottle the
plastic bags everything is hydrocarbon
the paint's that he used to paint our
house was also hydrogen cng Gramps she's
used to run auto rickshaws that is also
hydrocarbon
so let's start to classify hydrocarbons
now the hydrocarbons are classified into
two types based on the carbon-carbon
bond but it is the L affecting
hydrocarbon or and the second is the
cyclic hydrocarbon so any pending
hydrocarbons will have straight chain
they won't be having cycles and they
won't be having a circular ring kind of
structure and any fighting hydrocarbons
we have alkenes there is no double bond
all single bonds bit in common carbon
and then we have alkene where you have
once double bond between carbon carbon
and then we have alkyne where you have
one triple bond carbon carbon if you see
the example of alkyne the we have
attained we have methane also there are
examples of alkyne alkane for alkyne we
have it he we have propane beauty these
are examples of alkene and for all kind
we have a trying to find it in if Jarrod
is in the previous classes we'll study
in more detail about alkanes alkenes
alkynes not about cyclic the bonds we
have a li cyclic and we have aromatic so
aromatic is one which has sounds a row
mind which has a body called
4n plus 2 pi electrons and they have
more stability right they have most
resonance and then we have a li cycle
little bit further classic like le
slightly compound actually here skews
early cycling's they have closed frames
but their behavior is all similar to
aliphatic
their property they are all similar to
aliphatic compounds alright and if I
take another one they have open chain hi
I don't have wings if you see here there
is no ring this guy is happening but a
property physical properties resembles
then those of aliphatic and they
automatically have different orbitals so
let's further classify my an aliphatic
sorry a cyclic compound so in cyclic
component you see you can classify a
cyclo alkane cyclo alkanes and
cycloalkanes alkanes alkenes and we'll
see more examples of each cyclo alkanes
there is no double bond on all saturated
saturated example we have cyclopentane
then we have cyclo alkene where you have
one double bond there is cyclo pentene
one example and you have cycle alkyne
and in that you have a cyclo pentene as
an example here you have a triple bond
right similar to a leaky tokino kind
here we have cyclo alkanes cycloalkanes
cyclo alright correct no I have two one
about saturated and unsaturated
hydrocarbon this you discussed the last
two you chuck a video also saturated
means you have all single bond together
this guy's all saturated right there is
no double bond all single one or
stinking or we can say signal models
correct and these two are by unsaturated
because they have double bonds double on
little more
CBC eath in all single bonds are
straight you see there is a double bond
it's unsaturated this is the time you
see is a triple bond it's unsaturated
