List-I (Molecule / Species) | List-II (Property / Shape) |
---|---|
(A) \(SO_2Cl_2\) | (I) Paramagnetic |
(B) NO | (II) Diamagnetic |
(C) \(NO^{-}_{2}\) | (III) Tetrahedral |
(D) \(I^{-}_{3}\) | (IV) Linear |
(A) SO$_2$Cl$_2$: Hybridization is sp$^3$, Tetrahedral shape.
(B) NO: Unpaired electron, hence Paramagnetic.
(C) NO$_2^-$: Paired electrons, hence Diamagnetic.
(D) I$_3^-$: Linear shape with sp$^3$d hybridization.
A body of mass 1000 kg is moving horizontally with a velocity of 6 m/s. If 200 kg extra mass is added, the final velocity (in m/s) is:
