Answer:
(1)NBS, ROOR (2)
and (3)HBr, ROOR
Explanation:
Conversion of ethylbenzene to (2-bromoethyl)benzene involves three steps.
First step: allylic bromination of ethylbenzene in presence of NBS, ROOR. This step produces (1-bromoethyl)benzene.
Second step: E2 ellimination of HBr from (1-bromoethyl)benzene in presence of a strong base e.g. potassium t-butoxide []. This step produces styrene
Third step: HBr addition to double bond in presence of HBr, ROOR (antimarkonikov addition of HBr). Thus step produces (2-bromoethyl)benzene.
Full reaction scheme has been shown below.
The solution will be acidic if it contains a greater concentration of hydronium ions and acidic if it contains a greater concentration of hydrogen ions. So High concentrations of hydrogen lead to low pH(acidic) whereas low levels of hydrogen ions result in in a high pH(basic)
The actual formula for volume for a cube is the length multiplied by the width and then multiplied by the height. Since all three measurements are the same, the formula results in the measurement of one side cubed. For the example, 5^3 is 125 cm^3. Multiply the volume by the known density, which is the mass per volume.
