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 $HF$ are symmetrical.
In the light of the above statements, choose the most appropriate answer from the options given below.

Select pair of compounds in which both have different hybridization but have same molecular geometry

Statement I : According to wave mechanics, the atomic orbitals can be expressed by wave functions which represent the magnitude of the electron waves. These are obtained from the solution of Schrodinger wave equation
Statement II : The magnitude of H-bonding depends on the physical state of the compound. It is maximum in the gaseous state and minimum in the solid state
