it reacts with golden yellow shineno in chlorine too, check your books
another mark for explanation yeahThere were definitely 6 marks for the 3 conditions, 2 marks for each, 1 marks for stating that the rate of formation increases and another mark for stating how......i think so.
thanks ur a life saver!!!There were definitely 6 marks for the 3 conditions, 2 marks for each, 1 marks for stating that the rate of formation increases and another mark for stating how......i think so.
what burns with golden yellow shine? Sodium?it reacts with golden yellow shine
Its only 2 marks so u will lose them all i guess because the trick was about the skeletal formulaWonder how many marks would have been lost if i drew the cis trans isomers in the usual displayed formula rather than skeletal formula? :/
