QJEEM21Ch9d42: JEE Main 2021 Chemistry - Class 11 JEEM21Ch9d42 Solution: Given below are two statements : one is labelled as Assertion A …
Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : Dipole-dipole interactions are the only non-covalent interactions, resulting in hydrogen bond formation.
Reason R : Fluorine is the most electronegative element and hydrogen bonds in HF are symmetrical.
In the light of the above statements, choose the most appropriate answer from the options given below :
Assertion A : Dipole-dipole interactions are the only non-covalent interactions, resulting in hydrogen bond formation.
Reason R : Fluorine is the most electronegative element and hydrogen bonds in HF are symmetrical.
In the light of the above statements, choose the most appropriate answer from the options given below :
Multiple Choice Options
- A Both A and R are true and R is the correct explanation of A
- B A is true but R is false
- C A is false but R is true
- D Both A and R are true but R is NOT the correct explanation of A
Step-by-Step Verified Solution
Dipole - Dipole are not only the interaction responsible for hydrogen bond formation. Ion-dipole can also be responsible for hydrogen bond formation.
F is most electronegative element and anhydrous HF in solid phase has symmetrical hydrogen bonding.
