In an experiment, m grams of a compound X (gas/liquid/solid) taken in a container is loaded in a balance as shown in figure I below. In the presence of a magnetic field, the pan with X is either deflected upwards (figure II ), or deflected downwards (figure III ), depending on the compound X . Identify the correct statement(s).

Options

  1. AIf X is H 2 O ( l ) , deflection of the pan is upwards.
  2. BIf X is K 4 Fe ( CN ) 6 ( s ) , deflection of the pan is upwards.
  3. CIf X O 2 ( g ) , deflection of the pan is downwards.
  4. DIf X is C 6 H 6 ( l ) , deflection of the pan is downwards

Correct answer

A. If X is H 2 O ( l ) , deflection of the pan is upwards.

Step-by-step solution

Paramagnetic substance attracted by magnetic field so magnetic balance show downward deflection. While diamagnetic substance show repulsion in magnetic field show magnetic balance show upward deflection. Compound Magnetic Nature Deflection ( a ) H 2 O Diamagnetic Upward ( b ) K 4 Fe ( CN ) 6 Diamagnetic Upward ( c ) O 2 ( g ) Paramagnetic Downward ( d ) C 6 H 6 Diamagnetic Upward
