Polar Covalent Bonds - Carbon & its Compounds Video Lecture - Class 10

hello I'm an oxygen atom I would like to
tell you a little bit about myself I'm
hanging around the earth in the form of
an invisible odorless yeah no not that
kind of gas I'm talking about gas I mean
not solid or liquid yeah that's me right
there
Hey well I guess you can't fool because
I'm invisible
right you can't see me I look like man
I'm pretty important to most living
things because I help them reduce the
energy from their food molecules humans
and some other animals even grieve me in
Wow this kid is really a suck-up huh get
it stuck up oh it's got green in a
little too much that looks like a bird's
eye makeup about 21% of the air so I'm
all around you okay I'm in front of your
face right now but you can see me
because I'm so small I don't really have
a face I'm sad I am protons and neutrons
in my new clean in my room you're making
of electron orbit around my nutrients in
what we call energy levels or shells
technically I look like this a big
picture even is much fun so we're gonna
go with the shot of me with a hey okay
well my life you can always one big
party let me tell you why sometimes I am
so sad well we Adam strive to have our
outermost energy level filled with
electrons when I'm not binding to any
other atom I only have big electrons in
my outer energy level it really makes me
back
I kind of feel like Ron Weasley
oh no meaning incomplete because he baby
loves Hermione but he's afraid of color
sad man he's one broke and that made him
feel worse yep that's how I feel when I
don't have eight electrons in my outer
shell and it being I'm not the only one
all the other atoms out there feel the
same way when their outer levels are
full of electron there's one now thank
you Jeannie her outer level is the first
level which can hold a maximum of two
electron but she's only got one she's so
sad just like me she kind of feels like
Hermione she really loves mine and heals
incomplete without him Thank You Frankie
saying because Ron's kinda well you know
he's not the sharpest tool in the shed
and she's really smart but she runs in
anyway and him yep backpal
hydrogen-filled without a full outer
shell of electrons oh there's another
one behind again working just bad oh I
have an idea I need two more electron
each of you hydrogen atom had only one
electron if I share one of my electron
from each of you and you share yours
with me then you'll both have outer
shells that will be full I'm sure what I
mean what do you say hydrogen wanna give
it a try
what packaging you can print me
I feel so much better now we have to
stay close like me so we can keep
sharing big electron I'm feeling a real
bond with you both back I don't think
I'm quite myself anymore actually now
that we are bonding we are no longer
invisible dancing we are water main a
new and different stuff when we bonding
together you and me no matter how they
tossed the dice it had to be the only
one for me is you and you for me
so happy together
oh sorry
tonight emotional outburst but we're
pretty happy together
anyway I have a confession to make about
myself not many people know that about
me but I'm going to let you in on a
little secret
now it took me a long time and many
meetings and be able to admit me but I'm
an electron huh I know it's hard to
believe because I'm such a nice guy and
all but that's what I am the hydrogens
don't came to mind though
so what I didn't leave I to be
negatively charged electron flying
around my new place way more than the
nuclei of the hydrogen atom and it makes
my side of the water molecule a little
negative
hydrogen side at the water molecule and
that being a little bit positive since
the electrons don't sting as much turn
around them these weird little symbols
mean a little bit or partially when part
of a molecule is hydrogen while the
other part of it is negative it called a
polar molecule and that's what I am I'm
water
I'm a polar molecule polar molecules can
do some really cool things so it's
awesome to be colder it's one of the
cool things I can do this a friend polar
when other molecules and are polar get
near me like other water molecules the
positive hydrogen side of them is
attracted to the negative oxygen side of
me like this mmm misuk come on hydrogen
bond it's just an attraction between
slightly positive hydrogen one water
molecule and it slightly negative sign
I'm another one at molecule like me it's
not the kind of bond where there's
electrons being shared
just a little attraction it's a pretty
weak bond to it can break pretty easily
and when another one in Milan still gets
near it will form another hydrogen bond
with me like this attraction between us
rock on baggage and bond and that's what
makes water each water molecule
it's like a molecule hang around me if
you don't believe me I can prove it to
you make a penny and slowly drop water
on to me
the water won't fall off make sure you
have a huge amount of water on top this
is because behind you can bond between
the water molecules keep the water
monstro
together we're sticking to each other
don't you sound another way to prove
that I'm speaking and by looking at the
surface of me or even on your car when
it rains you don't have a water appears
to like round up or bead up on those
surfaces it's because of those hydrogen
line try dropping some water onto a
piece of wax paper and you'll see what I
mean
another cool thing about being polar is
it all kind of molecule with their
charge to dissolve any like sugar and
stop oh well I hope you learned a lot
about me oxygen and how I share electron
with two atoms of hydrogen to form water
I hope you learned a lot about water -
because without it weird goners
imagine we knew I do I think about you
day and night you're nothing but a big
baby with big pants on
