Review the verified answer and explanation for this SPSC – Sindh Public Service Commission past-paper question on CampusFin.

Which of the following bonds would show the strongest absorption in the IR? Answer: Oxygen-hydrogen

Oxygen is highly electronegative compared to hydrogen, creating a strong polar bond. This high polarity results in a large dipole moment, leading to intense absorption in the infrared spectrum. The O-H bond also frequently participates in hydrogen bonding, further enhancing its absorption.
