Polarity Worksheet AnswersFor each of the following pairs of molecules, determine which is most polar andexplain your reason for making this choice:1) carbon disulfide OR sulfur difluoridecarbon disulfide is nonpolar2) nitrogen trichloride OR oxygen dichlorideboth are polar, but oxygen dichloride is less symmetric than nitrogentrichloride, making it more polar.3) boron trihydride OR ammoniaboron trihydride is nonpolar.4) chlorine OR phosphorus trichloridechlorine is nonpolar5) silicon dioxide OR carbon dioxideIt’s a tie, because both are nonpolar6) methane OR CH 2 Cl 2methane is nonpolar7) silicon tetrabromide OR HCNsilicon tetrabromide is nonpolar8) nitrogen trifluoride OR phosphorus trifluorideBoth are polar and equally symmetric, but the difference inelectronegativity between N-F is less than that between P-FFor chemistry help, visit www.chemfiesta.com© 2007 Cavalcade Publishing; All Rights Reserved
