Questions from General Chemistry

Q: What do we mean by ionic bonding? Give an example of

What do we mean by ionic bonding? Give an example of a substance whose particles are held together by ionic bonding. What experimental evidence do we have for the existence of ionic bonding? In genera...

Q: What do we mean by covalent bonding and polar covalent bonding?

What do we mean by covalent bonding and polar covalent bonding? How are these two bonding types similar and how do they differ? What circumstance must exist for a bond to be purely covalent? How does...

Q: In the formation of a polynucleotide (a short portion of the

In the formation of a polynucleotide (a short portion of the DNA molecule), which components (sugar, base, or phosphate) on adjacent nucleotides bond to each other?

Q: What is meant by electronegativity? How is the difference in electronegativity

What is meant by electronegativity? How is the difference in electronegativity between two bonded atoms related to the polarity of the bond? Using Fig. 12.3, give an example of a bond that would be no...

Q: What does it mean to say that a molecule has a dipole

What does it mean to say that a molecule has a dipole moment? What is the difference between a polar bond and a polar molecule (one that has a dipole moment)? Give an example of a molecule that has po...

Q: How is the attainment of a noble gas electron configuration important to

How is the attainment of a noble gas electron configuration important to our ideas of how atoms bond to each other? When atoms of a metal react with atoms of a nonmetal, what type of electron configur...

Q: Give evidence that ionic bonds are very strong. Does an ionic

Give evidence that ionic bonds are very strong. Does an ionic substance contain discrete molecules? With what general type of structure do ionic compounds occur? Sketch a representation of a general s...

Q: Why does a Lewis structure for a molecule show only the valence

Why does a Lewis structure for a molecule show only the valence electrons? What is the most important factor for the formation of a stable compound? How do we use this requirement when writing Lewis s...
