There are three compounds with the molecular  formula C2 H2 Br 2 . Two of these are polar and have  a dipole, and one has no dipole (it is not polar).  Draw structural formulas for these three compounds and explain why two are polar and the  third is not.

Structural Isomers: In the next part you will learn a little about structural isomers and how to draw them. Structural isomers are compounds with the same molecular formula, but different bonding arrangements or connectivities. In other words, the atoms are connected in a different order. For example, there are 2 different compounds with the molecular formula C4H10. They are given below: H H-C- H -H H H HHH H- H H-C -H Η ΗΗ H H Do you see how the atoms are bonded in a different order in the 2 structures? So they are structural isomers. C3H12 Find three different molecular structures, isomers, with this formula. (Hint: Remember the C rule where every C atom needs to have 4 bonds.) C2H60 Find two different molecules with this formula. (Hint: What are the 2 ways you can C5H10 How many structural isomers can you find for this formula? (Hint: Notice that 2 H atoms have been removed. This means that there is EITHER 1 double bond OR there is a ring structure.) Try to provide at least 4…
