    June 2011 Q 3diii) when it says "...reacts with water" it means one water molecule?

    And I never get why they draw the molecules out the way they do, could someone explain?

    Nucleophile- contains a lone pair of electron which it can donate to form a bond. Attracted to areas of positive charge

    Electrophile- Electron deficient, attracted to areas of negative charge.

    Are these definitions enough to get the marks? I'm not really happy with the look of the electrophile one in particular

    OMG thank you so much!

    Primary/Secondary alcohols -> Halogenoalkanes= c. HCl+ High temperatures (reflux)

    Tertiary alcohols -> Halogenoalkanes= c. HCl at room temperature (r.t.p.)

    I ttthhiinnkkk going by the june 2011 mark scheme that primary/secondary alcohols to halogenoalkanes is just HCl (not conc) and high temp, and the conc HCl is for tertiary alcohols at room temp, though i'm not certain

    What is the difference between photodissociation (photolysis) and homolytic bond fission? Or is photodissociation a type of homolytic bond fission?

    Where are you getting the 4f from? Iodine is nowhere near the f block.
    I can't see his post but it only asks for the outer electron shell so it's just 5p^6 (superscript for the 6)

    water is made up of OH and H so when the double bond breaks, each carbon can make another bond and you have H and OH, so they can go on either carbon.

    Photodissociation can cause homolytic (radicals) or heterolytic (ions) bond fission

    I think that's right someone please tell me if its wrong

    Double bond if from the second carbon (that's where the 2 comes in), so it would be C-C=C-C (with the hydrogens)

    Doesn't photodissociation always cause radical formation though? I've never seen ions being formed from UV
