Question
In phosphorus acid, if X is number of non bonding electron pairs. Y is number of $\sigma$-bonds and Z is number of $\pi$-bonds. Then, calculate value of "Y \times Z - X".
π‘ Solution & Explanation
Step 1: A chlorine atom (electronegativity = 3.0) will exhibit a partial positive charge (delta+) when it is bonded to an atom with a higher electronegativity. Step 2: Compare the electronegativities of the bonded atoms: H (2.1), Br (2.8), S (2.5), Cl (3.0), and O (3.5). Step 3: Since oxygen (3.5) is more electronegative than chlorine (3.0), oxygen pulls electron density towards itself in OCl2, leaving a partial positive charge on the chlorine atoms. Thus, option (c) is correct.
