Which of the following attain the linear structure ?

`Be Cl_(2)`

`NCO^(+)`

`NO_(2)`

`CS_(2)`

Text Solution

Verified by Experts

The correct Answer is:

C, D

`BeCl_(2) (Cl-Be-Cl) and CS_(2) (S=C=S)` both are linear `NCO^(+)` is non-linear . However, remember that
`""^(-)NCO(""^(-)N= C = O )` is linear because it is isoelectronic with `CO_(2)`.
`NO_(2)` is angular with angle `132^(@)` and each O-N bond length of `1.20Å` (intermediate between single
and double bond) .

Which of the following equation is linear ?

`(dy)/(dx)+xy^2=1`

`x^2(dy)/(dx)+y=e^x`

`(dy)/(dx)+3y=xy^2`

`x(dy)/(dx)+y^2=sin x `

Which of the following equation is linear ?

`dy/dx + xy^2 =1`

`x^2 dy/dx +y = e^x`

`dy/dx +3y = xy^2`

`x dy/dx +y^2 = sinx`
