AP Biology Exam Review Unit 1 Questions and Answers What is a hydrogen bond? One of the weak chemical bonds that are central to the chemistry of life; a hydrogen bond is characterized by the non-covalent attraction between a hydrogen and an electronegative atom. When a hydrogen atom is covalently bonded to an electronegative atom, the hydrogen atom has a partial positive charge that allows it to be attracted to a different electronegative atom nearby. Typically, it is attracted to nitrogen or ...

AP Biology Exam Review Unit 1 Questions with Verified Answers How does hydrogen bonding allow for cohesive behavior in water? At any given moment, many of the molecules in liquid water are linked by multiple hydrogen bonds, which collectively hold the substance together and make water more structured than other liquids. This allows for adhesion (the clinging of one substance to another) and a relatively high surface tension (a measure of how difficult it is to stretch or break the surfa...
