Hydrogen bonding is an important intermolecular force in which of these? PH3, CH2F2, CH2O2, CH3COOH, H2O?

I would say CH2O2 (I'm assuming you mean formic acid, not dioxirane), CH3CO2H, and water.  \n\n"Important" is a tough word here, as all of these compounds can participate in h-bonding to varying degreees, with water being the strongest and CH2F2 being the weakest.  That said, strong hydrogen bonding gives rise to many of the nifty properties of water and in all three cases the h-bonding is powerful enough to raise the boiling points to be significantly higher than what you would expect based on molecular weight.

Water molecules participate in hydrogen bonding (H-bonds). The number of H-bonds formed in water increases with decreasing temperature. \n\nWhen the mocules freeze, this bonding causes them to align in a relatively ordered crystal lattice. The molecules could be closer together if it weren't for the H-bonds but with them, the lattice is the most stable configuration.\n\nAn ordered crystal lattice has more space in it than the molecules in liquid phase water, hence the expansion.

Hmmm.. The one affecting the boiling point is the intermolecular force..\nAs you can see, most of the compound here is polar. \n\nTherefore all you have to do is if the compound is consisted only of 2 elements (Group 17), you'll have to calculate the electronegativity difference. The more difference between them, the boiling will increase as well.\n\nIf there is more than 2 atoms in a molecule, you'll have to see the dipole moment magnitude (a.k.a polarity). The higher the magnitude, the higher the boiling point will be.\n\n\npeace\nvixklen

CH2Cl2\nThe molecule shape is tetraedric with the carbon in the middle

OH-(aq) + HC2H3O2(aq)---> H2O(l) + C2H3O2-(aq)

The bonding will indicate both of these. \na) CH3OH - sp3 O - H single bond\nb) CO32- sp2 O-H 1/3 double bond character through resonance\nc) CO2- sp C - sp2 O, double bond\nd) CO - sp C - sp O, triple bond\nThen longest to shortest is: a) b) c) d)\nWeakest to strongest is: a) b) c) d)

Becaue water is polar and water molecules form hydrogen bonds with each other.

methyl alcohol has all 3 intermolecular forces: dispersion, dipole and hydrogen bonding. the way your question is worded is unusual. molecular forces don't cause liquids to evaporate, they prevent it.

The Hydofluoric Acid i.e. HF has the strongest Cationic Hydrogen Bond.\nAnd I think I fogot the Binding Energy of it\nNo Problem I will tell U Later when I Read my book

There are 3 types of bond in sugars :\n\n1) -C-H (Covalent)\n2) -C-0H (Partially ionic)\n3) -C-O-C- (Covalent)\nand vander-waals force of attraction.

This is a classic result of intermolecular forces.  \nCO2 is a nonpolar molecule, meaning that molecules of CO2 have very little attraction between other molecules of CO2, so they like to be separate and just float around as gases.  (The only intermolecular force affecting CO2 is London dispersion, the weakest one.)  \nSiO2, on the other hand, is a network solid, which means that each unit of SiO2 is covalently bonded to another SiO2 unit, and covalent bonds are always stronger than any intermolecular force.  That's why it's a solid.

well this question was asked two days before.\nsearch for this question u'll get all the knowledge\nstrongest oxo-acid-- HClO4\nstrongest protonic acid--H2SO4\nstrongest lewis acid----SBF5\n btw HF is not consider very strong bcoz F is very small atom and it does not loose H+ very easily.\n\nEDIT: Question(very odd name) there has been acids with negative pH and 0 pH( 0pH is more stronger than 1)

an easy example you can remember is H2O(water).\nif u want a more difficult one, u can use CH3COOH(acetic acid)!\n\nALL DE BEST!

When the two glucose molecules join, two hydrogen and one oxygen atoms are released, so I think the answer to your question is that the larger molecule is the maltose and the smaller is water (H2O).\n\nHope this helps - now get on with your homework!!  ;-)
