Isoprene (2-methyl-1,3-butadiene) is a branched-chain unsaturated hydrocarbon, unsaturated meaning it contains one or more double bonds between carbon atoms. Isoprene has in fact two carbon-carbon double bonds. Isoprenoids contain from two to many thousands of isoprene units. Which structure is that of isoprene? Isoprene is a hemiterpene with the formulaRead More →
It is noticeable that the solubility of urea in a mixture of ethanol and water increases with increasing temperature and decreases with increasing ethanol concentration to the mixture. The fact that the solubility decreases with decreasing temperature at low pressures is attributed to the reduction in density 19. Does ureaRead More →
By forming the double helix, the DNA gets the nitrogenous bases (these are AGTC) out of water and into the center where they don’t have to interact with water so much. The simple answer is that nucleic acids will form double helicies in water (if they can) so as toRead More →
The simplest soluble form of silica, orthosilicic acid ‘Si(OH)4‘, is a weakly acidic molecule (pKa 9.8) with silicon tetrahedrally coordinated to four hydroxyl groups . Why is sio2 insoluble in water? Silicon dioxide does not consist of separate molecules that can dissolve individually into water. The SiO units are covalentlyRead More →
Chloroacetic acid, industrially known as monochloroacetic acid (MCA), is the organochlorine compound with the formula ClCH2CO2H. This carboxylic acid is a useful building block in organic synthesis. It is a colorless solid. Is trichloroacetic acid a liquid? Trichloroacetic Acid is a colorless, crystalline (sand-like) solid which is used in liquidRead More →
Biphenyl is a colourless to yellow solid with a pleasant odour. It is soluble in alcohol, ether, benzene, methanol, carbon tetrachloride, carbon disulfide, and most organic solvents. It is very slightly soluble in water. Is benzophenone soluble in methanol? Benzophenone, which is largely nonpolar, but possesses a polar carbonyl group,Read More →
p-Anisidine condenses readily with aldehydes and ketones to form Schiff bases, which absorb at 350 nm. This colorimetric reaction is used to test for the presence of oxidation products in fats and oils, an official method for detecting them by the American Oil Chemists’ Society. What is p-Anisidine value? Para-anisidineRead More →
Hexylene glycol is a key solvent in many markets such as coatings, construction, detergency, cosmetics & fragrances, textiles & leather. HGL is mainly used as a solvent or coupling agent. It is a potential substitute for glycol ethers. Is hexylene glycol an organic compound? Hexylene glycol is a colourless liquidRead More →
Ethyl alcohol shows presence of hydrogen bonding as well as it is polar due to high EN of oxygen , due to this it is soluble in water. Why does ethanol does not dissolve in water? Because there are fewer water molecules available to make hydrogen bonds with the alcoholRead More →
Primary Reason for Low Solubility The primary reason benzoic acid dissolves only slightly in cold water is that, even though the carboxylic acid group is polar, the bulk of the benzoic acid molecule is non-polar (water is polar). It is only the carboxylic group that is polar. What is theRead More →
