1.

The correct order among the following is/areA. `P lt Cl lt S (l.E_(2))`B. `HClO gt HBrO gt HIO` (Decreasing order of acidic nature)C. `Ti^(2+) lt Ti^(3+)` (Magnetic moment)D. `F gt O gt N gt C` (order of E.A)

Answer» Correct Answer - C::D
`(A) B lt C (E.A)`
`B^(+) gt C^(+)(l.E)`
`2s^(2) 2s^(2) 2p^(1)`
`(B) S lt Cl (E.A)`
`S^(+) gt Cl^(+)(l.E)`
`3p^(3) 3p^(4)`
(C ) `Li gt Na (E.A)`
`Li^(+) gt Na^(+)(E.A)`
`1s^(2) 2s^(2) 2p^(6)`
(D) `Na gt Mg (E.A)`
`Na^(+) gt Mg^(+) (l.E.)`
`2p^(6) 2p^(8) 3s^(1)`
