Which of the following compounds are non-polar compounds?Group of answer choicescarboxylic acidsamidesestersalkanes PreviousNext

Among the given options, alkanes are non-polar compounds.

Here's why:

1. Carboxylic acids: These are polar because they contain a polar carboxyl group (-COOH), which has a polar covalent bond due to the difference in electronegativity between oxygen and hydrogen.

2. Amides: These are also polar because they contain a polar amide group (-CONH2), which has a polar covalent bond due to the difference in electronegativity between nitrogen and hydrogen.

3. Esters: These are polar as well because they contain a polar ester group (-COO-), which has a polar covalent bond due to the difference in electronegativity between oxygen and carbon.

4. Alkanes: These are non-polar because they consist only of carbon and hydrogen atoms bonded together by non-polar covalent bonds. This is because the difference in electronegativity between carbon and hydrogen is very small, making the bond essentially non-polar.
