Chemical Bonding and Molecular Structure question

2021 · 26 Feb · Shift 1 · Q6

JEE MainChemistryChemical Bonding and Molecular StructureMCQ+4 / −1
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 :
  1. A
    Both A and R are true and R is the correct explanation of A
  2. B
    A is true but R is false
  3. C
    A is false but R is true
  4. D
    Both A and R are true but R is NOT the correct explanation of A
