    The polarity of the bonds do change down the group the polarity increase and the polarity is not measured for rate because it depends on the strength of the bonds not ability of atom to pull the shared electrons to its side not sure tho 😏
    Lol polarity decreases down the group 😂😂😂😂😂 it doesn't increase

    Wtf was that BS edexcel, i swear down this system is bs to the point youve had enough ,They say unit 2 and where are they asking questions from.They should include mechanisms reactions of halogens formation of bleach,reactions of halides ,Why are they putting questions from things from unit 3.What was the need of unit 3 then.2nd ionization energies ....Hydrogen bonding ....aldehydes ketones .Why do they tell us to review these things and they dont include it .Half of this was just structural drawing .And to make it even worse they have some stupid grade bounderies. Some kids are taking these subject just to achieve a C,NO but they have some grade boundaries which make no sense whatever.40 IS a D .Really if edexcel are so good with there calculations theyll realize thats half the mark and thats more then enough.So **** this ******** system and there papers.One more thing may i add nobody on the internet Ed excel based studying help.Look at khan academy and Ap chemistry ull find millions of resources.This has to change or someone should speak up.

    While i think mean titre is higher and iodine lower because it contained lesser percentage of iodine hence more iodine left in the solution to be titrated
