HF have both London force and hydrogen bond . But hydrogen bond is more significant than London force . So it's b.p must be higher than CH4 which has only London force .

Ayeee...I knew I was gonna get that one wrong..the other 3 were fine. Should have just written it had hydrogen bonding too
I gave few reasons for the difference in boiling temperature in all four compounds . But Im not sure whether my points gonna match with the mark scheme.

That's the problem...Edexcel keeps on changing what type of answer they want from the candidate. In 1 markscheme they'll give 1 answer and for the same question next session, they'll expect something else. I wrote at least 2 to 3 different versions of answers for most questions being on the safe side

But one thing I'm sure about new specification is that they don't accept answers from the old syllabus. So reading and making points from book is really important. At least they will one question of 6 marks from the book .

True...they had many this time. Only have Physics P2 left on 20th Jan..apart from that, I'm finished
