This regioselectivity can be changed against steric effects (Brown & Zweifel, 1960; Brown & Sharp, 1968; Brown et al., 1974). The existence of two active sites in methyl esters of fatty acids, FAME: the carbon-carbon unsaturation and the ester, make their hydroboration reactions more difficult to achieve.
1-propanol and 2-propanol can be best distinguished by: 1. Oxidation with alkaline KMnO4 followed by reaction with Fehling solution. 2. Oxidation with acidic dichromate followed by reaction with Fehling solution 3.

1-Propanol is a colorless liquid with a strong, unpleasant odor. It has a boiling point of 97.2 degrees Celsius and a melting point of -126 degrees Celsius. It is soluble in water and has a density of 0.804 g/cm³. In contrast, 2-Propanol is also a colorless liquid but has a milder, sweet odor.
Here you can find the meaning of 1-Propanol and 2-propanol can be best distinguished by (2001S)a)oxidation with alkaline KMnO4 followed by reactionwith Fehling solutionb)oxidation with acidic dichromate followed by reactionwith Fehling solutionc)oxidation by heating with copper followed by reactionwith Fehling solutiond)oxidation with concentrated H2SO4 followed byreaction with Fehling
Water is more polar than 2-propanol, so 40% 2-propanol in water is more polar than 60% 2-propanol. This is due to the electronegativity of the atom bonded to oxygen. Since hydrogen is less electronegative than carbon, it is easier for the oxygen to pull electrons towards itself in water, than it is for the oxygen to pull electrons from carbon
(ii) Benzaldehyde (C 6 H 5 C H O) and acetophenone (C 6 H 5 C O C H 3) can be distinguished by iodoform test. Acetophenone, being a methyl ketone on treatment with I 2 / N a O H undergoes iodoform reaction to give a yellow ppt. of iodoform. on the other hand, benzaldehyde does not give this test. other alcohols such as 1-propanol, 2-propanol, 1-pentanol and 2-pentanol, from 0.1 MPa to 100 MPa and four isotherms from 293.15 K to 353.15 K for both propanols and six isotherms from 293.15 K to 373.15 K for both pentanols. In addition, densities for these compounds were measured, from 0.1 MPa to 100 MPa and- Ոгը сቄзо
