AP Biology Exam Review Unit 1 Questions and Answers

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 ...
