The inequation that best describes the graph given below is _________

Options

A. `(ii) gt (iv) gt (i) gt (iii) gt (iv)`
B. `(v) gt (ii) gt (i) gt (iii) gt (iv)`
C. `(ii) gt (v) gt (i) gt (iv) gt (iii)`
D. `(v) gt (ii) gt (i) gt (iv) gt (iii)`

Answer

A

Explanation

Presence of electron–withdrawing (–I or –M group) like `-NO_(2)` at p–position will decrease the basicity, so (ii) will be the least basic, whereas presence of electron– donating (+I or +M) group like `OCH_(3)` at p–position in (iv) will increase the basicity so (iv) will be the most basic. Hence correct order of increasing basic character is (ii) < (v) < (i) < (iii) < (iv)
