a.

Summary Introduction

To explain: Whether nitrogen molecules contain non-polar or polar covalent bonds.

Introduction: Chemical bond is a force through which two or more atoms join together to form a molecule. Ionic bond, metallic bond, and covalent bond are the three main types of chemical bonds.

b.

Summary Introduction

To explain: Whether ammonia molecules contain non-polar or polar covalent bonds.

Introduction: A covalent bond is formed by sharing of valence electrons by two atoms to complete their outermost or valence shell to form a molecule. The number of covalent bonds an atom can make depends on the number of electrons it needs to completely fill its valence shell.

c.

Summary Introduction

To explain: Whether methane molecules contain non-polar or polar covalent bonds.

Introduction: Chemical bonds link atoms together in a particular arrangement that defines the type of molecules. It is an attractive force that arises between two atoms to unite atoms as a molecule. Electronegativity difference between the atoms determines the type of bond they can form in between them.

d.

Summary Introduction

To explain: Whether formaldehyde molecules contain non-polar or polar covalent bonds.

Introduction: The separation of charge into different positive and negative regions is called polarity. The polarity of a bond increases with an increasing difference in electronegativity. The electronegativity is defined as the ability of an atom to draw electrons away from another atom.
