Chemical reactions of Three Isomers of Butanol
September 24. 2013Order now
Purpose: The intent of this lab is to prove the reactions of primary. secondary. and third intoxicants with acid and with an oxidising agent.
chemical safety goggles
dropper bottles including:
K permanganate solution. KMnO? ( aq ) ( 0. 01 mol/L )
concentrated hydrochloric acid. HCl ( aq ) ( 12 mol/L )
protective baseball mitts
trial tubing rack
1 ) Appropriate safety dress including chemical safety goggles. apron. and protective baseball mitts were put on.
2 ) Three trial tubings were placed in the trial tubing rack. From the dropper bottles. two beads of butan-1-ol was placed in the first trial tubing. two beads of butan-2-ol were placed in the 2nd trial tubing. and two beads of 2-methylpropan-2-ol were placed in the the 3rd trial tubing.
3 ) Under the fume goon. the instructor oversing the schoolroom added 10 beads of concentrated hydrochloric acid to each of the three trial tubings. The mixtures were gently shaken. The trial tubing rack and trial tubings were returned to the lab bench. The tubings were allowed to stand for one minute and grounds of cloud cover was observed. These observations were recorded.
4 ) The oversing teacher’s instructions were followed refering the
disposal and cleansing of the contents of each trial tubing.
5 ) Three trial tubings were set up once more. as described in measure 2. This clip. four beads of each intoxicant were used.
6 ) 20 beads of K permanganate solution was carefully added to each trial tubing. Each mixture was gently shaken.
7 ) The trial tubing were allowed to stand for five proceedingss with occasional. soft shaking. The coloring material of the solution in each tubing was observed and recorded.
