Web1. A solvent can be protic or aprotic. 2. A solvent can be polar or apolar. 3. A solvent can be a donor or a nondonor. A protic solvent consists of molecules that can act as hydrogen-bond donors. Water, alcohols, and carboxylic acids are examples of protic solvents. Solvents that cannot act as hy-drogen-bond donors are called aprotic solvents. WebOct 4, 2024 · Exercise 7.9. 2.

WebNov 19, 2011 · Hydrogen-bonding interaction in acetonitrile oligomers is studied using density functional theory method. Two types of hydrogen-bonded oligomers are considered viz. cyclic and ladder. Different levels are used to optimize the geometry of acetonitrile monomer and found that at B3LYP/aug-cc-pvtz level the geometrical parameters and … WebAcetonitrile used as a Solvent. In terms of solvability, acetonitrile is a strongly polar solvent that is comparable to alcohols. Like alcohols, acetonitrile is a strong acceptor of hydrogen bonds rather than a donor of hydrogen bonds. Acetonitrile nitrogen is slightly basic, although it can be quite nucleophilic in this regard, akin to pyridine.
