Chemistry - CHEMICAL BONDING Question with Solution | TestHub

The %s character in each orbital of As for As-H bond of AsH₃ is 2%. The %s character in lone pair of AsH₃ is _____.

Explanation:

In AsH₃, there are three As-H bonds and one lone pair. The total %s character for the four hybrid orbitals (three bonding, one lone pair) must sum to 100%.

Given %s character in each As-H bond orbital = 2%.

Total %s character from three As-H bonds = $3\times 2\%=6\%$.

Therefore, the %s character in the lone pair orbital = $100\%-6\%=94\%$.

The final answer is $\boxed{94}$.
