Consider the structures of cyclohexanol and cyclohexene Are they both water soluble? Explain! which has the higher boiling point? Relate the differences in bailing points and solubility in water to intermolecular forces. 11. will cyclohexene or cyclohexanol be the first to exit or be detected by a gas chromatograph if the separation is based on boiling point? Explain why you think this is the case. first due its

Explanation / Answer

m = 25 g of cyclohexanol

MW = 100.158 g/mol

mol of cyclohexanol = 25/100.158 = 0.249605 mol

so expect... 0.249605 mol of cylohexene

MW of cylohexene = 82.143 g/mol

mass of cylcohexene = 0.249605 *82.143 = 20.5033 g of cylohexene

b)

m = 2.43 g of product...

yield --> real / theoretical * 100% = 2.43/20.5033 *100 = 11.851 %
