Part III. Single Replacement. With the following reactions, evidence of a reaction may not be immediately apparent. Before making a decision be sure to let the reaction stand for approximately 10 minutes. If no reaction occurs, write, "NO RXN" in under balanced chemical equations; Do not Wrile products or other equations. 1.

In our experiment we will use three different substrates: 1°,
n-butyl chloride; 2°, sec-butyl chloride; and 3°, tert- butyl
chloride, and we will evaluate their reactivity and the rate of the
reaction in an SN1 reaction. We will use an acid-base indicator to
monitor the completion of the reaction and a salt, silver nitrate,
to obtain a precipitate. The success of the reaction is evidenced
by the change in color of the indicator (from orange to red) due to
the...
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
d. Suppose you mistakenly acidify the filtrate with HCl instead of with HNO3. What would you obser after completing the halide test, and what would that observation lead you to conclude? Organic Laboratory Technique Primer Sodium Fusions and lon Testing Background: The elements that commonly occur in organic compounds along with carbon, hydrogen, and oxygen, are: nitrogen sulfur, and the halogens. The detection of these latter three elements depends on converting them into water soluble lons (CNS , and X...
