Question 1
Hydrogen will form a non-polar covalent bond with an element that has an electronegativity value of A 0-9 B 1-5 C 2-2 D 2-5
Worked Solution & Example Answer:Hydrogen will form a non-polar covalent bond with an element that has an electronegativity value of A 0-9 B 1-5 C 2-2 D 2-5 - Scottish Highers Chemistry - Question 1 - 2019
Step 1
Identify the Range of Electronegativity for Non-Polar Bonds
Answer
To form a non-polar covalent bond, the difference in electronegativity values between the two atoms must be very small, typically less than 0.4. This means that hydrogen can interact with nonmetals that have similar electronegativities.
Step 2
Examine Each Option for Compatibility
Answer
The given options are as follows:
- A: 0-9 (not informative, as this range is too broad)
- B: 1-5 (includes values that may not result in a non-polar bond)
- C: 2-2 (this is a specific value and has low electronegativity difference)
- D: 2-5 (too high, as it may lead to polar bonds)
Among these, Option C, which provides a specific value of 2.2, aligns with the criteria for forming a non-polar covalent bond.
