An aqueous solution of X is added slowly to an aqueous solution of Y as shown in Column I. The variation in conductivity of these reactions is given in Column II. Match Column I with Column II and select the correct answer using the codes given below the Columns.

Options

A. P-3, Q-4, R-2, S-1
B. P-4, Q-3, R-2, S-1
C. P-2, Q-3, R-4, S-1,
D. P-1, Q-4,R-3, S-2

Explanation

When `Et_3N` solution is added to `CH_3COOH` `'alpha'` of `CH_2COOH` will increase, so though `H^(+)` ions will be consumed by `Et_3N` but overall no. of ions in the solution will increase and hence conductivity increase intially.
`Ag_((aq))^(+)+NO_(3_((aq)))^(-)to AgI_((s))downarrow +H_((aq))^(+)+NO_(3_((aq))^(+)`
Number of ions remain the same so, conductivity does not change much. After all `Ag^(+)` ions have been precipated out, then the conductivity will increase .
`K_((aq))^(+)+OH_((aq))^(-) underset to(CH_3COOH(aq))H_2o(l)+K_((aq))^(+)+CH_3COO_((aq))^(-)`
Number of ions remain the same, but number of `OH^(-)` ions decreases and hence conductivity decreases.
`H^(+)+I^(-) underset to(NaOH) H_2o(l) Na_((aq))^(+)+I_((aq))^(-)`
Numbe of ions remains the same, but number `H^(+)` decreases and hence conductivity decreass.
