Question:

Match List-I (Molecule) with List-II (Interatomic Forces): 

List-I (Molecule)List-II (Interatomic Forces)
(A) HCl 
(B) o-nitrophenol 
(C) \( N_{2} \) 
(D) p-nitrophenol 

Show Hint

"Ortho" usually means "Internal" (Intra), while "Para" means "between neighbors" (Inter) for H-bonding.

The Correct Option is C

Solution and Explanation


Step 1: Concept
Identify the nature of molecular polarity and the possibility of hydrogen bonding.

Step 2: Meaning
(A) HCl: Polar molecule $\rightarrow$ Dipole-Dipole. (B) o-nitrophenol: H and NO2 are adjacent $\rightarrow$ Intramolecular H-bonding. (C) $N_2$: Non-polar $\rightarrow$ London dispersion (Induced dipole-Induced dipole). (D) p-nitrophenol: H and NO2 are far apart $\rightarrow$ Intermolecular H-bonding.

Step 3: Analysis
Mapping: A-IV, B-III, C-II, D-I.

Step 4: Conclusion
This matches perfectly with Option (C). Final Answer: (C)
