For group 16 elements, the atomic radii increases down the group as a shell of electron is added on each time.
If the trend is linear, that is boiling point increases by a constant amount for each additional saturated carbon, the boiling point of octane would be 69*2 because you are adding two saturated carbons. So the predicted boiling point is 138C, which is very close to the literature value
B I hope it’s right I don’t really help a lot but yeah lol
