Given below are two statements: one is labeled as Assertion (A) and the other is labeled 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 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 are symmetrical.
In the light of the above statements, choose the most appropriate answer from the options given below.
View answer and explanation
Correct option: A
A is false but R is true.
Option A is correct because the assertion is false as dipole-dipole interactions are not the ONLY non-covalent interactions, and the reason is true.
