नाइट्रोजन या ऑक्सीजन जैसे समनाभिकीय द्विपरमाणुक अणु में निम्नलिखित में से किस आणविक कक्षक (molecular orbital) की ऊर्जा बिल्कुल समान होती है?

Identify the correct statement about chlorine trifluoride (ClF3) from the following options:

Assertion (A): The bond angle in water (H2O) is 104.5°, which is less than the tetrahedral angle of 109.5°, and water has a significantly higher boiling point (100°C) than hydrogen sulfide H2S (−60°C) despite H2S having a higher molecular weight. Reason (R): Oxygen in water has two lone pairs that exert greater repulsion on bonding pairs than the lone pairs of sulfur in H2S, compressing the H–O–H bond angle; additionally, the high electronegativity of oxygen (3.5) compared to sulfur (2.5) creates a large dipole moment in water, enabling extensive intermolecular hydrogen bonding that requires significantly more energy to overcome during vaporization.
