    how can you tell if the imf's in a covalent compound are permanent dipole dipole with just the simple formula of a compound?

    Does the molecule consist of more than one type of atom, in which case there will be dipoles?

    Is the molecule symmetrical, in which case the dipoles will cancel out?

    Can you work out the shapes of molecules?

    i can work out the shape of molecules, so if theres more than one type with an asymmetrical structure, then there are permanent dipole dipole interactions?
    thanks

    That's good enough for A-level.

    Which exam board are you taking?

    Linear, trigonal planar, square planar, tetrahedral, trigonal bipyramidal, octahedral = symmetrical.

    Non-linear, pyramidal (all types), T, see-saw = asymmetrical.
