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. WebAprotic solvents are solvents that can accept hydrogen bonds. Aprotic solvents do not have acidic hydrogen. Polar Aprotic solvents can dissolve salt. Their ability to dissolve salts depends strongly on the nature of the salt. SN2 reactions are significantly faster in polar Aprotic solvents than in protic solvents. dunajska streda thermal
