Question

What is polar and non polar compound and how they are further divided into aprotic and protic give example

Solution

Dear Student,.... Polar compounds are compounds that have slight charges (slightly positive and slightly negative) within the compound. The slight charges are due to electronegativity differences of 0.3 to 1.4. Nonpolar compounds are compounds that do not have slightly negative and positive charges within the compound. The electronegativity differences of nonpolar compounds are between 0 and 0.2. Polar protic solvents are capable of hydrogen bonding because they contain at least one hydrogen atom connected directly to an electronegative atom (such as O-H or N-H bonds). They solvate cations and anions effectively. Polar protic solvents are water, ethanol, methanol, ammonia, acetic acid, and others. Polar aprotic solvents contain no hydrogen atoms connected directly to an electronegative atom and they are not capable of hydrogen bonding. These are acetone, dimethyl sulfoxide, DMF (N,N-dimethylformamide), acetonitrile, HMF (hydroxymethylfurfural), crown ethers and others. Regards.
