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.

The... show more Consider the following statements and determine which are true and which are false.1.Selenium tetrafluoride (SeF4) is a non-polar molecule.2.KrF4 is a polar molecule. 3.Carbon tetrachloride (CCl4) is a polar molecule 4.NO3- has only two resonance Lewis structures. 5.Bond angles for IF6+....Carbon tetrachloride (CCl4) is a polar molecule:- False The four bonds of carbon tetrachloride (CCl4) are polar, but the molecule is non-polar because the bond polarity is cancelled by the symmetric tetrahedral shape.
