Bond Polarity and Electronegativity
Chemistry ⇒ Chemical Bonding and Structure
Bond Polarity and Electronegativity starts at 10 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Bond Polarity and Electronegativity.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11
Arrange the following bonds in order of increasing polarity: C–H, O–H, N–H.
Calculate the difference in electronegativity between hydrogen (2.1) and oxygen (3.5).
Define electronegativity.
Describe how the concept of electronegativity is useful in predicting the type of bond formed between two atoms.
Describe the relationship between bond polarity and molecular polarity.
Describe the trend of electronegativity across a period in the periodic table.
Explain why CH4 is a nonpolar molecule even though it contains polar bonds.
Explain why CO2 is a nonpolar molecule even though it contains polar bonds.
Explain why the C–Cl bond is more polar than the C–H bond.
Explain why the H–Cl bond is polar.
If the electronegativity difference between two atoms is 0, what type of bond is formed?
The electronegativity of sodium is 0.9 and that of chlorine is 3.0. What is the electronegativity difference?
Which element has the highest electronegativity value?
