Linear structure is assumed by:
(I) `NCO^(-)` (II)`CS_(2)` (III)`overset(+)(N)O_(2)` (IV)Solid `BeH_(2)`

The correct stability order of the following resonance structure is : (I) H_(2)C= overset( +)(N) =overset( -)(N) (II) H_(2)overset( +)(C )-N = overset( -)(N) (III) H_(2)overset( -)(C ) - overset( +)(N) = N (IV) H_(2)overset( - ) (C ) -N = overset( +)(N )

The correct order of stability of the following resonance structures is (I) H_(2)C = overset(+)(N)= overset(-)(N) " " (II) H_(2)overset(+)(C )-N = overset(-)(N) (III) H_(2)overset(-)(C )-overset(+)(N)-=N " " (IV) H_(2)overset(-)(C )N = overset(+)(N)

Which of the following have linear structure I. SnCl_(2) II. BeF_(2) III. SO_(2) IV overset(+)NO_(2) C_(2)H_(2)

The correct stability order of the following resonance structures is (I)H_(2)C = overset(+)N = overset(-)N" "(II)H_(2)overset(+)C - N = overset(-)N (III)H_(2)overset(-)C - overset(+)N = N" "(IV)H_(2)overset(-)C - N = overset(+)N

A posible mechanism for the reaction : 2NO + 2H_(2) to N _(2) + 2H_(2) O is : (i) 2NO + overset(k _(1))hArr N _(2) O _(2) (ii) N _(2) O _(2) + H _(2) overset(k _(2))to N _(2) O + H _(2) O (iii) N _(2)O + H _(2) overset(k _(3)) to N _(2) + H _(2)O If the second step is the rate determining step then rate law may be written as : ?

Which of the following canonical structures cannot represent resonance forms of N _(2)O molecule ? (l) :overset(* *) (N) = N = overset(* *) (O): (ll) :N -= N - underset(* *) overset(* *) O: (lll) : underset(* *) overset(* *) (N) - N -= O : (lV) : overset(* *) (N) = O = overset(* *) N: (A) I and II (B) II, III and IV (C) IV (D) III and IV

The correct stability order of the following resonance structure is: {:(CH_(2)=C=O,H_(2)overset(-)(C)-overset(+)(C)=O,H_(2)O=overset(+)(C)-overset(-)(O) , H_(2)overset(-)(C)-C-=O),((I),(II),(III),"(IV)"):}
