Compound A (C 7H 11Br) is treated with magnesium in ether to give B (C 7H 11MgBr), which reacts violently with D 2O to give 1-methylcyclohexene with a deuterium atom on the methyl group C. Reaction of B with acetone (CH 3COCH 3) followed by hydrolysis gives D (C 10H 18O). Heating D with concentrated H 2SO 4 gives E (C 10H 16), which decolorizes two equivalents of Br 2 to give F (C 10H 16Br 2). E undergoes hydrogenation with excess H 2 and a Pt catalyst to give isobutylcyclohexane. Determine the structures of compounds A through F, and show your reasoning throughout.

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !

your parents i think this could be it
