Question 12 (1 point)
Hexane and hex-1-ene are both colourless liquids. One method used to
differentiate between hexane and hex-1-ene is to add a few drops of
orange-coloured aqueous bromine to samples of each organic compound.
Hexane is
i hydrocarbon, and hex-1-ene is _ii hydrocarbon.
The statement above is completed by the information in row
i-a saturated
ii- an unsaturated

Question 17 (1 point)
Sunscreens may contain para-aminobenzoic acid (PABA). The PABA in the sunscreen absorbs
ultraviolet (UV) radiation from the Sun, which can cause damage to the skin. After swimming,
a person must reapply a sunscreen containing PABA because PABA is water soluble. PABA is
represented by the structural diagram below.
