Chemistry Paper 4 Question

[Ritter]

Hi,

Could anyone please explain to me how to answer the following question:

This is O.L Chemistry Paper 3 November 2004

I know the first box is C6H12
I am asking about the boiling point, I'd like to know how to get it, and also how to predict any boiling point in any question not just this one, whether there's a method or something to get it.

Thanks in Advance.

I solved it 60 with my teacher
I don,t think it has a method to be solved with , it is just predicting by seeing the previous numbers

If so, then why did the mark scheme write such a small range (60 to 65)?
