In the fractional distillation of crude oil, how does boiling point change as the chains get longer?IncreasesRemains constantBoiling point is independent of chain lengthDecreasesQuestion 6 of 10 Loading... 7. What is meant by the term viscosity?The viscosity of a fluid describes how easily it flows. Water has a low viscosity, it flows very easily. Crude oil has a higher viscosity than water, it does not flow very easily.The viscosity of a fluid describes how easily it flows. Water has a high viscosity, it flows very easily. Crude oil has a lower viscosity than water, it does not flow very easily.The viscosity of a fluid is how easily it evaporates. Refinery gases evaporate easily, they have high viscositiesThe viscosity of a fluid is how easily it evaporates.

A student has been asked to draw all the alkene isomers of C₄H₈ and draws the following. Which of the following statements about the student's diagram is correct?The displayed formulae are correct, and the names are: 1) but-1-ene 2) but-2-ene and 3) methylpropene.The displayed formulae are correct, and the names are: 1) but-1-ene 2) but-2-ene and 3) methylpropene. However, the student has forgotten to also draw cyclobutane.The student is wrong because the molecules labelled 1 and 2 are the same molecule, so not different isomersThe displayed formulae are correct, and the names are: 1) but-1-ene 2) but-2-ene and 3) methylbutene.Question 9 of 10 Loading... 10.
