Can propyl isobutyrate also be called propyl 2-methylpropylate?

Propyl isobutyrate, by which I assume you mean n-propyl iso-butyrate, has many common names including:\n\nPropanoic acid, 2-methyl-, propyl ester; Isobutyric acid, propyl ester; Propyl isobutyrate; Isobutyric acid n-propyl ester; n-Propyl 2-methylpropanoate; Propyl 2-methylpropanoate; Propyl isobutanoate\n\nThe NIST chemistry webbook has all of this stuff online for free.

1-Propanol. CH3CH=CH2 + B2H6 ===> CH3CH2CH2-BH2 ===> CH3CH2CH2-OH.\n\nDiborane always adds with the H on the more highly substituted carbon. This is the opposite of the Markovnikov rule during reaction with H2O and a little H2SO4, where the H goes to the less highly substituted carbon to give 2-propanol.

It varies with the grade produced.  This example is is 94.5 nitromethane with nitroethane and nitropropane.  I doubt there is any measurable amount of propane left in the commercial product.

Isopropyl alcohol is not a product of any living organism.  Some bacterial produce ethanol, but not isopropyl alcohol -- which, by the way, is somewhat poisonous.

I'm guessing this is a question for class. In practice, working with acetylene gas as a synthetic reagent isn't a good idea. It's a flammable, explosive gas and most synthetic labs really don't have the necessary safety equipment to handle it. It's much safer to buy the butyne you need and work from there.\n\nHowever, on paper you would first make the 2-butyne. You would react 1 eq of acetylene with 2 eq of n-BuLi followed by quenching with 2 eq of MeI and standard workup and purification. If you want the 1-butyne, you can isomerize 2-butyne to 1-butyne with an amide base like NaNH2 or KHMDS.  The reason you can't just alkylate with iodoethane is that you are going to end up with a mix of acetylene, 1-butyne and 3-hexyne since you can't selective monodeprotonate every acetylene molecule. \n\nHope this helps.

a.  1-Bromobutane will undergo a faster reaction than 1-chlorobutane, as bromide is a better leaving group than chloride, due to being a weaker base.\nb.  1-Bromobutane will undergo a faster reaction than 2-bromobutane, as primary halides undergo SN2 reactions faster than secondary halides, due to steric considerations.

A Synthesis of Safrole and o-Safrole\nW.H. Perkin & V.M. Trikojus\nJ. Chem. Soc. 1663 (1927)\nHTML by Rhodium\nNo direct synthesis of safrole has been recorded, the most recent attempt being that of Baker and Robinson (JCS, 1925, 127, 1424), who distilled the product of the action of silver oxide and water upon gamma-piperonylpropyltrimethylammonium iodide, but obtained isosafrole, the double bond moving into the position of greater stability. Kawai (Sci. Papers Inst. Phys. Chem. Res., 1925, 3, 263) has shown that the monoallyl ether of pyrocatechol undergoes the Claisen rearrangement to give an oil which he considered to be a mixture of 3- and 4-allyl-1,2-dihydroxybenzene.\n\nThis matter has now been reinvestigated and, by repeated fractionation of the product of the rearrangement, both of the above isomerides have been isolated in a pure state as colourless, crystalline solids melting at 28°C and 48°C respectively. As further confirmation of the course of the Claisen migration, it has been found that the properties of the higher-melting isomeride (II) are in accord with those assigned to the "4-allylbrenzcatechin" which Schimmel and Co. (Centr., 1907, II, 1741) isolated in small quantity from betel-leaf oil from Java. The second isomeride, 1,2-dihydroxy-3-allylbenzene (I), has not previously been described.\n\nIn order to convert these substances into safrole (III) and o-safrole (IV), respectively, methylenation was carried out, with moderately good yields, by gently refluxing them with methylene iodide and anhydrous potassium carbonate in dry acetone solution. By employing such mild conditions, any change into the isomeric isosafroles during the course of the reaction was inhibited. The identity of the synthetic product with naturally occurring safrole has been established by preparing the pentabromo-derivative (mp 169°C) and the acetamido-derivative (mp 162-163°C) and comparing these with the same derivatives from natural safrole. The properties of the hitherto unknown isomeride o-safrole (IV) (which resembles safrole in odour and in many other ways) have been recorded. The process of methylenation described above takes place very smoothly without formation of tarry products and may prove to be valuable in other cases of this kind.

No.  Ibuprofen, like other 2-arylpropionate derivatives (including ketoprofen, flurbiprofen, naproxen, etc) contains a chiral carbon in the α-position of the propionate moiety. As such there are two possible enantiomers of ibuprofen with the potential for different biological effects and metabolism for each enantiomer.

no, its propanoic acid - able to form h-bonds with water molecules and become dissolved.  propanal can also form h-bonds, but since propanoic acid has some delocalised electrons, attraction is greater.
