Why H-O-H bond angle in a water molecule is greater than H-S-H bong angle in H2S molecule?
Ans. The central atom of H2O is O and H2S is S. Due to the smaller size of oxygen, the electronegativity of oxygen is greater than that of S. In H2O molecule, the central atom of oxygen has four electron pairs in which two pairs are bonding pairs and two pairs are lone pairs. In … Read more
