Question

Which has maximum number of atoms of oxygen(a) 10 ml H2O(l)(b) 0.1 mole of V2O5(c) 12 gm O3(g)(d) 12.044 ×1022 molecules of CO2

Answer 1

Out of H2PO2, H2PO2 and H2PO4 which has the maximum number of P - H bonds?

In the first case all the hydrogen atoms are attached to oxygen atom as OH group from which hydrogen can be easily released as protons.

Hence,the acidity will be the highest.

As electron density of the O—H bond decreases, the bond becomes more polar.
