This is the reason whyacetonebecomes agood solvent for both polar and nonpolar substances, as thetwo nonpolar methyl groupsare also there.Moreover, theacetone’scentral carbon in the carbonyl group issp2-hybridized, which gives it aplanar structure around this atom. Thisplanerstructurealso significa...
What is a polar covalent bond? Is CH3OCH3 a polar molecule? What's the difference between a dipole and a polar molecule? Which molecule(s) contain(s) polar covalent bonds, but is(are) nonpolar? What is a polar solvent? Explain. ...
What is the molecular formula of acetone? What is solubility in physical chemistry? What is a pure substance in chemistry? The greatest solvent in the world is What is a compound in chemistry? What is dissolution in chemistry? What property of water allows water to work as a universal solven...
respectively, at oil concentrations ranging between 10 and 15 µl/ml. The oil showed a similar significant inhibitory effect againstSt. aureusin the microbiological media (2.0–6.0 log reduction), whereas
I assume this is just an Organic I or II lab. I think they are just looking for you to choose a polar solvent that is immiscible with water. Your logic for excluding methanol and acetone because of their complete miscibility is perfect. Ether and cyclohexane are nonpolar, so again, logical...
Therefore, a solution method was proposed to solve this difficulty. Solution method of the basic idea is that in infinite dilute nonpolar solvent solution, when the state of the solute molecules in the gas phase, and the infinite dilute solution of solute Moore polarizability EMBE 21、D Equation...
A base is a substance that dissolves in water: (a) to absorb OH- ions (b) to release OH- ions (c) to release oxygen molecules (d) none of these choices are correct Into which solvent do pigments dissolve best? a. Acetic acid b. Acetone c. Mineral d. Oil e. Water What is a ...
Chlorophyll a is easily soluble in ethyl alcohol, acetone, chloro- form, ether and carbon-disulphide, pyridin and benzene, moderately soluble in methyl alcohol and soluble with difficulty in 80% ethyl alcohol, 90% methyl alcohol (even warm) and petrol ether (even warm).In which solvent ...
Coating compositions in nonpolar vehicles having additive for adjusting electrical properties and method of using Coating compositions for electrostatic spraying comprise a solution of a film-forming material in an organic solvent and, dissolved therein, 0.0005-0.02% by weight of a mixture of (a) an...
The formation of relatively strongly hydrogen-bonded complexes between HOOOH and organic oxygen bases, HOOOH-B (B = acetone and dimethyl ether), strongly retards the decomposition in these bases as solvents, most likely by preventing such a proton transfer....
