Which of the Following Regarding Non-Covalent Bonds is a Correct

Question

Which of the following regarding non-covalent bonds is a correct?
A)All non-covalent bonds are formed between oppositely charged polar functions.
B)Hydrogen bonds,ionic bonds,and hydrophobic interactions all carry a degree of specificity,while van der Waals interactions are induced.
C)van der Waals interactions are not affected by structural complementarity,while hydrogen bonds,ionic bonds,and hydrophobic interactions are affected by structural complementarity.
D)Hydrogen,van der Waals,and hydrophobic interactions do not form linear bonds.

Accepted Answer

Hydrogen bonds, ionic bonds, and hydrophobic interactions involve specific interactions between polar or nonpolar functional groups, while van der Waals interactions arise from fluctuations in charge density around atoms and molecules and are not specific. Van der Waals interactions are also influenced by the complementarity of molecular shapes. None of these non-covalent interactions involve the linear bonding observed in covalent bonds.
