The objective of today's experiment is to detect the functional group present in the given organic compound. Apparatus required are. Testing folder spatula, test tube, beaker burner with tripod stand. Failing solution 8. Feeling solution. Ferrous chloride solution, sodium bicarbonate solution, sodium hydroxide 24 DNP solution and the given organic. Functional groups are the specific groups of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules. They define the reactivity and properties of organic compounds playing a crucial role in organic chemistry. They are the reactive part of the molecule governing reactions like oxidation, erosion, adhesion and soft situation. Some of the common examples of functional groups are aldehyde, alcohol, carboxylic acid, ether, ketone, etc. Now for the detection of physical characteristic. The given compound is in liquid state with a fair yellow colour and has a very almond bike order. Ohh, let's do this solubility test. That's stupid. Cold water. Give an organic compound. I was thinking. As you can see, it's not soluble in cold water. Now let's do the hot water test. As you can see, it's not soluble in hot water. We've done it at sea. We add one to two ML of the given organic compound. As you can see it is not soluble with XLS well. Now for sodium bicarbonate dish take 1-2 ML off given organic compound. Shake it. As you can see, it's not soluble in sodium bicarbonate compound now with alcohol. Can we add one to two ML of the given solution? Shake it well. And as you can see, it is soluble in alcohol. Now for the preliminary test, we'll start with litmus test. Here we have taken a blue litmus paper. We did in the organic solution. As there is no changing color, it indicates that the compound is neutral and it may be aldehyde or ketone present. Now let's do the English scientist. Take a spatula. Add some organic compound. Bonded in a Bunsen burner. At sooty flame etc. While burning it, so the compound may be aromatic. For sodium bicarbonate test take some given organic compound. Add 12 ML of sodium bicarbonate. Shake it up. As you can see there is no evolution of gas South. There may be absent of carboxylic compound. Now for big chloride test we take. One to two ML of the given solution. Then add 2 to 3 drops of the FCL 3 solution. A series of options of blue or green colour. It indicates that the absence of phenolic. Now for 24 DNP tests we take. Few drops of the organic solution, then we add 12 mill of the two four DNP solution. After miss mixing, we let it sit for 2:00 to 3:00 minutes. After 5 minutes, as you can see, we can absorb orange crystalline precipitate, which indicates the presence of carbonite group. Remarks The above preliminary test indicate a possible presence of either an aldehyde or ketone group. So confirmatory tests are required to accurately identify and differentiate between them. Now let's do the confirmatory test for functional group. Let's begin with the scriptures and test take some given solution. In the given solution, add some skips raising. Shake it up. As you can see, magenta colors has appeared. This indicates the presence of LVAD group. Reactions involved in the above test. This gives reagent plus aldehyde which gives a doc that is magenta color. Similarly, for the feeling solution tests, we take very failing solution A and failing solution B in the same test here. Shake it. And after that we take few drops off the organic compound. And then we let it warm up in a water bath. It's already been 5 minutes. Here we can see a red PPT found on the bottom of the deck. That confirms the presence of Aldehyde group in the compound. Aldehyde reacts with failing 3 agent to give red precipitate of cuprous oxide for tolling. Switch and test take two to three ML of tall in Swaziland. Add 12 level of solution. And he ate it for a few minutes in the water bath. It's been 5 minutes, let's see the results. As you can see, silver mirror coating has appeared on the inner wall of the festive. It confirms the presence of ALDI group reaction involved in the work test. LDID reacts with Tollens reagent and it gives silver mirror coating. Result. Thus, based on the above experiment, it is concluded that the given compound contains an aldehyde functional group. Conclusion. Thus, the functional group of a compound could be determined by performing various chemical tests.
