The electron dot-structure of H2O is underset(lps + σ - bps = 2 + 2 = 4) mathopH-- underset. . overset. . mathopO --H Hence, oxygen atom undergoes sp3 text- hybridisation. It should be tetrahedral, but due to presence of 2 lone-pairs of electron, it is angular with H?O?H, bond angle =104.5° .

Q. What is the structure of $H_{2} O$ ?

Tetrahedral

Pyramidal

Angular

Planar

The electron dot-structure of $H_{2} O$ is $(lp s + σ - b p s = 2 + 2 = 4) H - - . . O . . - - H$ Hence, oxygen atom undergoes $s p^{3} -$ hybridisation. It should be tetrahedral, but due to presence of 2 lone-pairs of electron, it is angular with H?O?H, bond angle $= 104.5^{\circ} .$
