In phosphorus acid, if X is number of non-bonding electron pairs. Y is number of -bonds and Z is number of -bonds. Then calculate value of "Y Z - X".

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 $	imes$ Z - X".

Correct 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. Step 1: Note that under anhydrous conditions, aluminium chloride exists as a covalent dimer, Al2Cl6. Step 2: Upon dissolving in water, the hydration of the aluminum center causes ionic dissociation. Step 3: According to the specific textbook solution key, this dissociation is represented by the formation of complex ions [AlCl2(H2O)4]+ and [AlCl4(H2O)2]-, matching option (c).
