In which of the following oxides of three elements X, Y and Z are correctly arranged in the increasing order of acidic nature. The electronic configurations of X, Y and Z are [ Ne ] 3 s^2 3 p^1,[ Ne ] 3 s^2 3 p^5 . [Ne] 3 s^2 respectively
Options
- AX < Y < Z
- BY < Z < X
- CZ < X < Y
- DX < Z < Y
Correct answer
C. Z < X < Y
Step-by-step solution
According to given electronic configuration, X is Al , Y is Cl and Z is Mg . Along a period, the basic nature of oxides decreases and acidic nature of oxides increases. Mg , Al and Cl belong to same period with Mg on left side f the period, Cl on the right side and Al in between them. Oxide of Cl is i.e. Y will be most acidic oxide of Mg , i.e. Z will be basic and oxide of Al , i.e. X in between the other two. Correct increasing order acidic nature will be Z < X < Y
