    35:22 why do we substitute again?? they said *ethane* reacts with chlorine and not *chlorethane* so in my opinion it should be D

      but, even the reaction of ethane with chlorine can give dichloroethane. in fact, there can be 4 different products in the substitution reaction of methane ; chloromethane, dichloromethane, trichloromethane and tetrachloromethane. I think for ethane there might be 6... but I'm not sure about Ethane

      ​@@spiderking0038but if dichloro is an answer shouldn't be h-h also be an answer since two H's were substituted?

      The reason why 3 is correct is because it didn't specify that the reaction has to be between ethane and chlorine, further substitution can still occur. As for why H-H is not considered a product it is because H-H reacts with the chlorine to become H-Cl.

      they didnt specify the time and amount of each reactant so the reaction will continue even to form other products like Tetrachloroethane hope that helps

    Dont understand Q39 why 3 is correct since if 3 us correct than 1 also has to be correct ??

    • @igcsewithhan
      @igcsewithhan  4 месяца назад

      1 is wrong because H-H further reacts with chlorine to produce H-Cl
