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?
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?
In phenol carbon is sp2 hybridised and due to this reason benzene ring is producing electron withdrawing effect. On the other hand, carbon of methanol is sp3 hybridised and produces electron releasing effect (+I effect). Thus, C−O bond in phenol is less polar than C-O bond in ...
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
The given compound dichloromethane is only slightly polar. Therefore, dichloromethane is incapable of getting solvated in water. The volatility...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your tough homework ...
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 ...
