im thinking it would be the nonpolar molecule...so A?
anonymous
  • anonymous
yup its A ...... because its non polar ..... we have hydrogen bonding in B, C and D
anonymous
  • anonymous
thus instantaneous-induced dipole forces are present between non polar molecule :D

c d and e dont have h-bonding o.O
anonymous
  • anonymous
sorry //// C , D , and E are POLAR
anonymous
  • anonymous
i misread the question :( //// but the answer is A
anonymous
  • anonymous
when flourine , chlorine, oxygen and nitrogen are present in a non symetrical molecule ... then it is polar
anonymous
  • anonymous
and polar molecule have permanent dipole
anonymous
  • anonymous
THUS A IS 110 % correct
lgbasallote
  • lgbasallote
idk how to prove c d and e are polar though
lgbasallote
  • lgbasallote
how do i prove they are polar?
anonymous
  • anonymous
you know something about dipole moment >????
lgbasallote
  • lgbasallote
all i know is drawing lewis...and it seems tedious
anonymous
  • anonymous
you know something about dipole moment >????
lgbasallote
  • lgbasallote
yes i know dipole moment...somehow
anonymous
  • anonymous
or relative electronegativity of elements
lgbasallote
  • lgbasallote
when the directions of the electronegativity in the lewis cancel out then zero dipole moment
anonymous
  • anonymous
FLORINE, CHLORINE AND OXYGEN .. are the MOST ELECTRONEGATIVE ELEMENT
lgbasallote
  • lgbasallote
mmhmm
anonymous

NO2 is polar because it has a lone electron
anonymous
  • anonymous
unbonded
lgbasallote
  • lgbasallote
yeah...i figured that one out already :D
anonymous

H2S is polar because of 2 lone pairs
lgbasallote
  • lgbasallote
H2S i think looks something like |dw:1343732893300:dw|
anonymous
  • anonymous
yup its shape is bent
lgbasallote
  • lgbasallote
calcium nitrate...idk how that looks
anonymous
  • anonymous
you dont need the structure ..... just look at the oxygen ... secondly ... it is non symmetircal ... thus it must be polar
lgbasallote
  • lgbasallote
hmm i see
anonymous
  • anonymous
|dw:1343733005262:dw|
lgbasallote
  • lgbasallote
lol enough with H2S we've already confirmed it's polar :p
lgbasallote
  • lgbasallote
C2H6 looks like this right.. |dw:1343733047139:dw| that's why it's nonpolar?
anonymous
  • anonymous
lgbasallote ..its a basic question :D
lgbasallote
  • lgbasallote
well im not chemistry inclined -_-
lgbasallote
  • lgbasallote
i can call laplace transforms basic but you wont right? ;)
anonymous
  • anonymous
|dw:1343733096534:dw|
lgbasallote
  • lgbasallote
hmm bottomline they cancel hehe
anonymous
  • anonymous
yup :D
lgbasallote
  • lgbasallote
so wait....if there are no lone pairs then i's nonpolar?
lgbasallote
  • lgbasallote
it's*
anonymous
  • anonymous
not necessarily ...
lgbasallote
  • lgbasallote
oh
anonymous
  • anonymous
its must be symmetrical
anonymous
  • anonymous
|dw:1343733217757:dw|
anonymous
  • anonymous
|dw:1343733238479:dw|
anonymous
  • anonymous
you see the difference :D
lgbasallote
  • lgbasallote
ohhhh
anonymous
  • anonymous
anyway ..we are done with this question
lgbasallote
  • lgbasallote
yeah i think so too
anonymous
  • anonymous
CLOSSSSSSSEEEEEEEEEE IIIIITTTTT
