10 Questions
What is the primary reason for the polarity in the bond between the hydrogen atom and oxygen atom in a water molecule?
The difference in electronegativity between hydrogen and oxygen is greater than 0.5.
Which of the following statements about the carbon-hydrogen (C-H) bond is correct?
The C-H bond is non-polar covalent because the difference in electronegativity is less than 0.5.
What is the primary reason for the strength of an ionic bond?
The atoms involved in the bond are in their ionic state (positively or negatively charged).
What happens to the ionic bond between sodium (Na) and chlorine (Cl) when water is added to sodium chloride (NaCl)?
The ionic bond becomes weaker and more fragile, eventually breaking apart.
What is the relationship between the difference in electronegativity and the type of bond formed between two atoms?
A difference in electronegativity of 0.5 or more results in a polar covalent bond.
Which of the following statements about the carbon-oxygen (C-O) bond is correct?
The C-O bond is polar covalent because the difference in electronegativity is greater than 0.5.
What is the primary factor that determines the strength of an ionic bond?
The ability of the atoms to form positive and negative ions.
Which of the following statements about the valency of an atom is correct?
Valency is the number of covalent bonds an atom can form with other atoms.
How does the strength of a covalent bond compare to the strength of an ionic bond?
Ionic bonds are generally stronger than covalent bonds.
What is the primary difference between a polar covalent bond and a non-polar covalent bond?
Polar covalent bonds involve the unequal sharing of electrons, while non-polar covalent bonds involve the equal sharing of electrons.
Test your knowledge on covalent bonds and valency in chemistry. Learn about the different valencies of elements like hydrogen, carbon, oxygen, nitrogen, phosphorus, and sulfur, as well as the characteristics of single, double, and triple covalent bonds.
