Isopropyl bromide was treated separately with sodium tert-butoxide and sodium ethoxide under two different condition. Reaction I : at 400C gave almost exclusively compound A, C3H6 Reaction II : at 300C gave compound A along with small amount of ether B, C5H12O. compound A was readily oxidized by a neutral solution of cold dilute potassium permanganate to give a brown precipitate. 5. Which type of reaction is used to explain the formation of A? 6. Draw the structure of the activated complex formed in reaction II that leads to compound A? 7. What happened when product A is treated with cold and alkaline KMnO4 . 8. Write the IUPAC name of compound B 9. Write the equation used to prepare isopropyl bromide
Suppose you wanted to analyse the amount of metal in alloy. For example, you might want to determine the nickel (Ni2+) content in alloy material.
(a) Using gravimetric analysis, propose precipitating method to analyze nikel (Ni2+) in alloy and write 8 steps required during the precipitation. Also suggest an appropriate solvent and its ratio to dissolve the mixture. Here we recommended to use dimethylglyoxime (H2DMG) as organic precipitating agent. (10 Marks)
(b) Suppose the nickel had been precipitated from the alloy (2.0980g) using dimethylglyoxime (H2DMG) as organic precipitating agent and giving a precipitate of complex nickel dimethylglyoxime (Ni(HDGMG)2) weighing 0.2370g. Calculate the percentage weight of nickel (Ni2+) in the alloy sample. (5 Marks)

What is the mole ratio (not the conversion factor, just the simple ratio) of molecular oxygen, O₂, to water, H₂O, in this reaction? 2H₂+ O₂ --> 2H₂O
Identify chiral molecules and explain how optical isomerism influences the effects of drugs – use the drug thalidomide as an example
En un tubo de vidrio, los electrones se mueven del electrodo negativo (cátodo) al electrodo positivo (ánodo) produciendo una zona brillante mediante la presencia de alto voltaje emana desde el cátodo. Indicó que el rayo catódico estaba compuesto de partículas diminutas con una carga eléctrica. Estas partículas tienen carga negativa y la relación carga/masa del electrón fue de -1.76 x 108 C/g.
