1.	Which of the trichlorides is hydrolyzed most easily?A. `SbCl_(3)`B. `NCl_(3)`C. `AsCl_(3)`D. `PCl_(3)`
Answer» Correct Answer - 2 The ease of hydrolysis depends upon the tendency of the control atom to attract the lone pair of electrons from water which decreases as the electronegativity of the central atom(`E`) in `ECl_(3)` decreases down the group . Thus, the ease of hydrolysis of trichlorids decreases in the order: `NCl_(3) gt PCl_(3) gt AsCl_(3) gt SbCl_(3) gt BiCl_(3)`
