This is because butterfly caterpillars are host specific. Plant-wise, the caterpillars of some butterfly species like asters, black-eyed Susan, clover, lupines, milkweed, sedum or violets. Aspen, birch, cherry, hackberry, oak or willow trees make caterpillars of other butterfly species equally happy.
each Br-F bond would be polar or BF4-, there is an extra electron making this a polar molecule. PCl5 has the Cl atoms that must be as far apart from each other as possible and therefore would create equal but opposite pulls.ach Br-F bond would be polar or BF4-, there is an extra electron making this a polar molecule.

Indicate in the column labeled âMolecular Polarityâ whether the molecule is polar or nonpolar. In the column labeled âBond Polarityâ indicate whether any of the bonds in the molecule are polar or if they are all nonpolar.(Leave the third column blank for now.ndicate in the column labeled âMolecular Polarityâ whether the molecule is polar or nonpolar.
