Anomalous Behaviour of Fluorine Video Lecture - NEET

hello friends this video on p-block part
44 is brought to you by exam for your
calm no more fear from exam no we have
seen fluorine special and so many case
let's chart down all the special things
about the flow'ry this is chlorine and
this is special see the first special
thing is about the fluorine is the
electronegativity if you see it has a
highest electronegativity value okay so
first we will see that it does the
highest electronegativity in fact in the
whole periodic table it has the highest
electronegativity and the value is 4 it
has very high in born or this associate
enthalpy we have seen that just now we
have seen that sorry very less you just
seen that just now we have seen 158 kilo
Joule per mole
compared to other it is less right and
electrode potential is very high
ionization energy is also a little less
here sorry the ionizer is very high it
is 16 80 kilo Joule per mole if you see
the ionization is very high power - so
it has high ionization energy electrode
potential is also very high potential is
also high size is very small we have
seen that very small signs and that is
reason for special behavior of fluorine
and the electron in enthalpy is quite
lower than expected we have seen that
the electron reading healthy so we have
seen expected value of electron meaning
that we should be more it should be
around 400 - 400 but actually it is
lower then the expected value why we
have seen that there is a repulsion
right in this 2p orbital they are 5
one 2p orbital it's really small the
person going on and there's the electron
beam enthalpy is lower than expected
electron expected okay and all these
behavior is actually because of very
small size and very high
electronegativity these two governs most
of the spec it doesn't have a D orbital
no D orbital in fact that is also reason
for a special behavior of fluorine and
it shows only minus 1 and 0 oxidation
state oxidation
C and 0 only in case of fluorine 0 in
only case of frame other it is only
minus 1 oxidation state okay then most
of the fluorine reactions are exothermic
most of my reactions are exothermic
it gives energy why because the small
and strong bond formed by fluorine with
other elements right and it forms only
one ox I said only one oxygen will we
will see that when we study this oxides
will see that fluorine form only one
oxide synthetase h4f this is the only
one access but other halogen you can see
forms large number of oxides if you talk
about HF special case adding fluoride
this is liquid at my 293 Kelvin
temperature why it is liquid because of
the strong hydrogen mod HF if you see it
has strong hydrogen bonds is slightly
negative slightly positive you talk
about another HF here it's like cleaning
it is slightly positive there is a
hydrogen bond correct so HF also is
different from another hydrogen halide
this study about these Inlet and because
of this hydrogen bonding Ashley my HF
is more stable than other hydrogen
halides okay this HF is more stable also
since it is more stable it is weaker
that said this is weaker acid as
compared to other hydrogen halide okay
now if we talk about oxidizing agent my
fluorine is better oxidizing engine as
compared to other halogens okay
one more special property god fluorine
is fluorine his neighbor his neighbor
central atom in any molecule why it is
so why fluorine is never a central atom
on any molecule why because see it is
moreover it at the max it can have only
one bond so typically fluorine is never
a central atom in any model why it is
bolo violence it is a monovalent can
form only one bond so only is never sent
