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.

Best Answer: The answer is CCl4, because I2 isn't polar at all (for symmetry reasons), and as you probably know, an unpolar substance dissolves well in a non-polar solvent.The most non-polar solvent in this list is CCl4, for symmetry reasons.Source(s): l3thargik Â· 7 years ago.est Answer: The answer is CCl4, because I2 isn't polar at all (for symmetry reasons), and as you probably know, an unpolar substance dissolves well in a non-polar solvent.
