(a) `F^(ɵ)`, (b). `Cl^(ɵ)`, (c). `Br^(ɵ)`, (d). `I^(ɵ)` (A). `a gt b gt c gt d` (B). `d lt a lt c lt b` (C). `d gt a gt b gt c` (D). `a gt d gt c gt b` (ii). (a). `CH_(3)^(ɵ)`, (b). `Cl^(ɵ)`, (c) `OH^(ɵ)`, (d). `F^(ɵ)` (A). `a gt b gt c gt d` (B). `d lt a lt c lt b` (C). `d gt a gt b gt c` (D). `a gt d gt c gt b` (iii). (a). `R-NH_(2)`, (b). `Ph-NH_(2)`, (c). `R-underset(O)underset(||)(C)-NH_(2)` (A). `a gt b gt c` (B). `a lt c lt b` (C). `a lt b lt c` (D). `a gt c gt b` (iv). (a). `NH_(3)`, (b). `MeNH_(2)`, (c). `Me_(2)NH` , (d). `Me_(2)N` (A). `a lt b lt c lt d` (B). `d lt a lt c lt b` (C). `d gt a gt b gt c` (D). `a gt d gt c gt b` |

Answer» Correct Answer - (i)A, (ii)A, (iii)A, (iv)A Basic strength : The anion which is less stable take more `H^(+)`. (iii). In option (B) & (C) 1. pair involve in resonance. (iv). In gas phase order `-3^(@)gt2^(@)gt1^(@)gtNH_(3)` |
