    How was Chemistry P1/2

    A straight-chain alkane will have a boiling point higher than a branched-chain alkane due to the greater surface area in contact, thus the greater van der Waals forces, between adjacent molecules.

    How was Chemistry P1/2

    well yes i had a doubt between the covalent and forces one !! but i went with the forces as i doubt that i had read that somewhere !! check this link : http://en.wikipedia.org/wiki/Alkane scroll down to the boiling point heading :) and than let me know plz :)

    in covalent bonds electrons are shared ?? ryt ?? so there can be attractive forces between those and the nuclei can't it ? :p

    thanku :D !! u might get 2 marks jus because of writing ACIDIFIED !! if the examiner takes it in account as acidic conditions :)

    How was Chemistry P1/2

    sure it is Doosh !! but they asked for a FULL structure !! got my words >?? FULL !! where is the O-H bond here ?? :P !! hope now u got it !!

    How was Chemistry P1/2

    the confirmed option is that copper always formed at cathode !! bet on it :)

    How was Chemistry P1/2

    pentane one was D , the forces of attraction always contribute to the boiling point !!.. while the methanol mcq was A !! it was also confirmed by the last question in p2 :) !! they asked for a FULL structure of methanol it was wrong as a bond between O-H was missing :) !! got it >? !! yup...

    How was Chemistry P1/2

    yup even if it is :) !! in a solution H+ and Cu 2+ ions would be there !! as copper is less reacrive than hydrogen they will always be preferentially discharged :) hope this helps :)

    How was Chemistry P1/2

    nope i said it in a very kind manner and in a fORmal way LOL :p !!! plus it's better if u admit !! 1 mark wrong won't take ur A* away :D
