AIIMS 2019 Botany Charophyceae MCQ Question
Select the correct diagram.
Correct Answer
Detailed Explanation
Option A accurately represents the molecular structure of water (H₂O), illustrating the bent geometry due to the two hydrogen atoms bonded to the oxygen atom at an angle of approximately 104.5°. This molecular shape is a result of the repulsion between the lone pairs of electrons on the oxygen atom, which is not depicted in options B, C, or D, leading to incorrect representations of water's polarity and hydrogen bonding capabilities. Understanding the molecular geometry of H₂O is crucial for grasping its unique properties, such as its high surface tension and solvent abilities.
