Three hydrocarbon samples, DDD, EEE, and FFF, have the molecular formulas C6H14\text{C}_6\text{H}_{14}C6H14, C5H10\text{C}_5\text{H}_{10}C5H10, and C4H8\text{C}_4\text{H}_8C4H8 respectively.
A student adds a few drops of orange bromine water to a sample of each hydrocarbon and shakes the mixture.
Predict the colour of each mixture after shaking and explain these observations by referring to the structure and bonding of DDD, EEE, and FFF.
