Polarity Practice Worksheet - Solutions For each of the following pairs of compounds, determine which is most polar based on their Lewis structures. 1) methyl chloride (CHCl 3 ) or methyl bromide (CHBr 3 ) Since chlorine is more electronegative than bromine, the molecule has a higher polarity. 2) water or hydrogen sulfide (H 2 S) Since oxygen is more electronegative than sulfur, the moelcule has a

Unformatted text preview: higher polarity. 3) hydrochloric acid (HCl) or hydroiodic acid (HI) Chorine is more electronegative than iodine, making HCl more polar. 4) bromoacetylene (C 2 HBr) or chloroacetylene (C 2 HCl) Chlorine is more electronegative than bromine, making chloroacetylene more polar. 5) methanol (CH 3 OH) or diethyl ether [(CH 3 ) 2 O] Since diethyl ether has the oxygen at the middle of the molecule rather than on the end, it is far less polar than methanol. 6) acetone [(CH 3 ) 2 CO] or propanol (C 3 H 8 O) A quick look at the Lewis structures of this molecule should convince you that acetone is far more polar, as the molecule appears more unbalanced.
