    Default protic solvent and aprotic solvent?

    I know you went over them in Sn1 and Sn2 lecture, but can you briefly explain them to me? with examples? thanks!

    Default

    Protic solvents are those that are capable of hydrogen bonding which ultimately then means they have to have O-H or N-H bonds in their structure. The most common examples of protic solvents would be water, alcohols, or carboxylic acids which all have O-H bonds in their structures.
    Aprotic solvents are those that are not capable of hydrogen bonding. A notable example is acetone which has an oxygen and it has hydrogens but it doesn't have an O-H bond in its structure (the oxygen is only bonded to the carbon) and is therefore incapable of hydrogen bonding and is therefore aprotic. The other common aprotic solvents include ethers (like diethyl ether or THF), DMF (dimethylformamide), DMSO (dimethylsulfoxide) and CH3CN (acetonitrile).
