Question
Chapter 9, Problem 17PDQ
Summary Introduction
To review:
The differences between covalent bond and hydrogen bond. Also, determine basecomplementarity.
Introduction:
A bond is an attraction between atoms, ions, or molecules. This interaction led to the formation of the chemical compound. This bond can be formed due to electrostatic force of attraction or sharing of electron. The strength of bond varies as it can be weak or strong.
