Why is methanol more toxic than ethanol? Why is carbon-13 stable? Why are chlorinated hydrocarbons dangerous to marine organisms? Why is diethyl ether a good solvent? Why is carbon significant to the formation of living organisms? How does toluene's chemical structure allow it to be such a ...
Why does sugar dissolve but not dissociate in water even though it is a polar molecule? Why is an acid catalyst used in the reaction between benzoic acid and methanol? Explain the buffer system used in buffered aspirin. For example, what is the chemical formula of the buffer that is used?
The carbon - oxygen bond in phenol is slightly stronger than that in methanol. Why? View Solution For a given mass and size, moment of inertia of a soild disc is smaller than that of a ring. Why ? View Solution View Solution View Solution ...
The best way to tell if something will dissolve is to look at the polarities of the solvent and the solute. If the polarities of the solvent and solute match (both are polar or both are nonpolar), then the solute will probably dissolve. If the polarities of the solvent and solute are...
1b) was solved in the solid state (pdb 2mlt)29 and in a methanol solution30. The peptide is tetrameric in the crystal in agreement with the data in aqueous solutions at high ionic strength31. The monomer in both the crystal and the solution structures consists of two helices interrupted ...
OH), methanol (CH 3 OH), isopropanol ((CH 3 ) 2 CHOH), dichloromethane (CH 2 Cl 2 ), ethyl acetate (CH 3 CO 2 C 2 H 5 ), acetone (CH 3 (CO)CH 3 ), toluene (C 6 H 5 CH 3 ), benzene (C 6 H 6 ), acetonitrile (CH 3 CN) and hexane (C 6 H 14 ). Sildena...
In this situation the wash solvent was altered to water which is a much more appropriate solvent for very polar molecules, as there are less solubility issues. As Joanne observed in this scenario the choice of the wash solvent was critical. However this also raises another important fact, ...
To understand why the dipole moment of phenol is smaller than that of methanol, we can break down the explanation into a series of steps.1. Identify the Structures: - Phenol: The chemical structure of phenol
Explain why methanol spontaneously evaporates in open air at 25.0 degree C. Why does the enthalpy of formation for the ethanol dimer have more energy than two isolated ethanol molecules? Why is it important to know the lattice enthalpy of different ice-melting salts? Why does the addition of ...
Why is methanol a good solvent to recrystallize biphenyl? Explain why coconut oil is a liquid triglyceride even though most of its fatty acid components are saturated. Why don't lipids and water mix? Why is dichloromethane used as a solvent?
