Question

which of the Following has strongest IMF of attraction ?
Hydrogen,chlorine,iodine,methane
need help :/
@.Sam. @AravindG @thomaster @nincompoop

Answer 1

@secret66 @Hero @Haseeb96 Anyone ? :/

Answer 2

Which of these has the greatest number of electrons?

Answer 3

Definitely H-H bond is more stronger than Cl and and I bonds.

Answer 4

@AravindG that's what I'm thinking . what is reason ?? :/

Answer 5

You could use MOT.

Answer 6

inter molecular forces ????

Answer 7

Extend of overlap of orbitals is more in H-H bond. Let me think how o explain it in terms of IMF.

Answer 8

ok . I'd to go . but please give explanation ^_^

Answer 9

i think Iodine

Answer 10

@Haseeb96 More attraction means more bond strength right? Halogens bonds have bond energy around 280 kJ while that of H-H bond is above 400.

Answer 11

oh yes

Answer 12

yes hydrogen has greatest hydrogen bond energy and this amount of energy produce when the nascent hydrogen combined and produce 400kj\mole in a reaction

Answer 13

IMF means Intramolecular or Intermolecular forces ???

Answer 14

Intermolecular forces, I guess.

Answer 15

inter molecular means then between h2-h2 not h-h ???

Answer 16

Yes.

Answer 17

then its not hydrogen , London forces are stronger in Iodine due to polarization .

Answer 18

The strongest of the IMF's is hydrogen bonding. It is NOT what holds 2 hydrogen molecules together (that is van der Waals). Hydrogen bonds occur between molecules that have a permanent net dipole resulting from hydrogen being covalently bonded to either fluorine, oxygen or nitrogen.

Answer 20

Please help @jigglypuff314 :(

Answer 21

Sarah, if your question is about intermolecular forces, then yes, iodine will have the strongest intermolecular forces because it has greatest number of electrons and so more ability to set up temporary dipoles.

Answer 22

yeah that's what I got now , If IMF means inter then its Iodine
Thank you @emcrazy14 ^_^

Answer 23

If it is about the strength of the bonds in these molecules, then H-H will be strongest. It has a value around 436 kJ/mol.

Answer 24

yeah but in that case if intra molecular
but here its inter molecular @emcrazy14
@ParthKohli

Answer 25

Because of the very small radius of H atoms, the shared electron pair is very strongly attracted to the hydrogen nuclei, thus the strong intramolecular forces.

Answer 26

Yes, this question is about intermolecular.

Answer 27

So its Iodine finally :D :D @emcrazy14

Answer 28

Yes, IODINE it is.

Answer 29

Thank you sooooooooooo much ^_^ @emcrazy14

Answer 31

:D thanks for tagging me ♣_♣ IMF b/w halogens increases down the group F<Cl<Br<I. that's it :D so Iodine is the answer and as for electro-negativity F>Cl>Br>I. Just try to remember the trend of periodic table and all this will be very very simple for you. @sarah786
