Answer 3-5

answer only 7and 8 thank you!

Need both of these!!!

Table 1 lists 33 pure compounds, several of which you will select to mix with each of your unknowns, so that you can determine the melting points of the mixtures, and thus the identity of the unknowns.   Table 1.  Known Compounds for Melting Point Experiment     COMPOUND mp range (oC)   COMPOUND mp range (oC)   1)   1,4-dimethoxybenzene   54-56        21)   4-nitroaniline   146-149   2)   2-phenylphenol   57-59        22)   1-napthoic acid   158-160   3)   diphenylacetylene   59-61        23)   salicylic acid   159-161   4)   2,4,6-trichlorophenol   64-66        24)   triphenylmethanol   160-162   5)   biphenyl   68-70        25)   sulfanilamide   165-167   6)   methyl 3-nitrobenzoate   78-80        26)   4-bromoacetanilide   165-169   7)   naphthalene   80-82        27)   itaconic acid   165-168   8)   vanillin   81-83        28)   d-mannitol   166-168   9)…

Give the correct COMMON name and spelling of the following compounds. Note proper notations (like hyphen and commas)

Please help! I need to know how to draw the full chemical structure of isoproyl red.  *I drew the structure of isopropyl alcohol (second pic) but was told this was incorrect and that the chemical structure needs to show a combination of methyl red and isopropyl alcohol.

Organic Functional Groups Identifying positions labeled with Greek letters in acids and derivatives If possible, replace an H atom on the a carbon of the molecule in the drawing area with a methyl group substituent, and replace an H atom on the ß carbon with a hydroxyl group substituent. If one of the substituents can't be added for any reason, just don't add it. If neither substituent can be added, check the box under the drawing area. HO Oneither substituent can be added. OH 0/5 X

Give the correct COMMON name and spelling of the following compounds. Note proper notations (like hyphen and commas)

Identify which compound will have higher boiling point using IMFA. Justify your answer in the given table.

4. Start with NH3 and show step-by-step how the compound N-sec-butyl-N-isopropyl-3-pentanamine can be formed. Draw and name the reactants and products in each reaction (3 separate reactions.) 5. Salicylic acid (shown below) is a polyfunctional molecule (contains more than one functional group.) Circle and identify the functional groups on salicylic acid. Salicylic acid can react with ethanoic acid (acetic acid) to form aspirin. It can also react with ethanol to form ethyl salicylate, a compound with a minty smell used in perfume and artificial flavors. Draw out structures to illustrate each of these reactions. Discuss how these two reactions are similar and how they are different. HO, HO
