- Calculate the contour length and the root-meansquare separation of the ends of the chain of polyethene with molar mass 250 kg mol-1.arrow_forwardA colorless solid that melts at 103 to 105 C was subjected to IR Spectroscopy to determine the functional groups present and partially determine its nomenclature based on the molecular formula given. What are the functional groups present based on the major infrared absorptions? (Select Possible Answers)arrow_forwardComplete the following table. In the second column, assign each set of molecules as constitutional isomers, conformational isomers, enantiomers, diastereomers, or identical. For the third column, based on that analysis, indicate for each set of molecules if they are separable or inseparable by SiO2 chromatography.arrow_forward
