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".
Answer: 0 / STRUCTURE OF H3PO3 HAS 6 LONE PAIRS (X=6), 6 SIGMA BONDS (Y=6), 1 PI BOND (Z=1). Y $\TIMES$ Z - X = 6 $\TIMES$ 1 - 6 = 0
