4.60 g of 3-hexanol were obtained from 5.33 g of hex-3-ene. Determine the percentage yield of 3-hexanol. a Determine the moles of hex-3-ene, , used in the experiment. (To avoid introducing rounding errors on intermediate calculations, enter your answer to four significant figures.)

Explanation:

C₆H₁₂     + H₂O      =     C₆H₁₃OH

hexene                      hexanol

1 mole                             1 mole  

Mol weight of hexene = 84

Mol weight of hexanol   = 102

5.33g of hexene = .06345 moles

4.6 g of hexenol = .0451 moles

percentage yield of hexanol

= .0451 x 100 / .06345

= 71.07 %

Moles of hexene used = .0451 moles
