Covalent diectional?

    covalent diectional??

    Covalent bond is directional because it is due to the orbital overlap and orbitals can overlap only in certain directions to give constructive interference. (This is true I hope! comments pls!) .
    My question is when two s-orbitals (from two atoms) overlap how can it be directional because s-orbitals have spherical symmetries and have no certain directions??

    Well of course it's still directional. It points from one atom to the other one.

    I'm agree. In molecular hydrogen, bond has an oval shape. It is possible to distinguish a symmetrical longitudinal axis and a transversal plan. Both of them include the origin of symmetry. You can also recognize it in all other non-ionic biatomical bonds, involving even now s-orbitals.
