Question

Weak chemical bonds such as hydrogen bonds __________.

A) form when a hydrogen atom that is covalently bonded to an electronegative atom like oxygen or nitrogen is attracted to another electronegative atom

B) are not important in biological systems

C) form when an oxygen atom that is covalently bonded to an electronegative atom like hydrogen is attracted to another electronegative atom

D) form when a hydrogen atom that is covalently bonded to a weakly electronegative atom like oxygen or nitrogen is attracted to another weakly electronegative atom

E) None of the listed responses is correct.

Answer 1

Hydrogen bonds form between a covalently bonded hydrogen atom in a polar molecule and another electronegative atom, playing a crucial role in biological systems.

Step-by-step explanation:

Weak chemical bonds such as hydrogen bonds form when a hydrogen atom that is covalently bonded to an electronegative atom like oxygen or nitrogen is attracted to another electronegative atom. In other words, hydrogen bonds are formed between a hydrogen atom which is part of a polar molecule, and another electronegative atom from a different molecule. These hydrogen bonds are important in biological systems for many functions, including stabilizing the structure of proteins and DNA.
