1Write the correct general formula for Alkanes (no spaces!)
C[blank_start]n[blank_end]H[blank_start]2n+2[blank_end]
- An
- B2n+2
2Write the correct general formula for Cycloalkanes (no spaces!)

3Complete these stages of the Fractional Distillation of Crude Oil:
Crude oil is vaporised at [blank_start]350[blank_end]C.
Crude oil goes into the Fractionating [blank_start]Column[blank_end] and rises up through it.
As the crude oil ascends, it cools and the various fractions are drawn off according to their boiling points.
[blank_start]Larger[blank_end] fractions don't evaporate at all but run out of the bottom.
[blank_start]Smaller[blank_end] fractions are drawn off as [blank_start]gases[blank_end] out of the top of the column.
