  • Is there any way in which we can remember all bond shapes with their hybridization state? Like sp3 has what shape...i need to memorize all them..so a tip would help

  • @kartikeyaable VSEPR and hybridization are connected by groups. See the following in order of Group/Hyb/Shape

    1 s linear (not really hybridized)

    2 sp linear

    3 sp3 trigonal planar

    4 sp3 tetrahedral

    5 sp3d trigonal bipyramidal

    6 sp3d2 octahedral

  • i dont get it, how do the dipoles cancel?! just because its symmetrical? and based on what do i place the atoms in a symmetrical way?

  • @ilovemyprs Yes, it is symmetrical. Or in other words, the bond dipoles are like vectors and there is no net vector. The problem asked for a nonpolar molecule. This molecule can also be drawn with a dipole if you switch a Cl with a F.
