Question

Quizplus · Accepted Answer

Hydrogen bonding can occur between different molecules or within the same molecule. This occurs whenever a hydrogen atom is attached to a highly electronegative atom, such as oxygen or nitrogen, and forms a weak bond with another electronegative atom nearby. This results in a partial positive charge on the hydrogen atom, which can attract the partial negative charge on another electronegative atom nearby, forming a hydrogen bond. This type of bonding is observed in many biological molecules, such as proteins and DNA, as well as in water molecules.
