Options

  1. AA wheel of radius 0.2 m rotates freely about its center when a string that is wrapped over its rim is pulled by force
  2. BA wheel of radius 0.2 m rotates freely about its center when a string that is wrapped over its rim is pulled by force
  3. CA wheel of radius 0.2 m rotates freely about its center when a string that is wrapped over its rim is pulled by force
  4. DA wheel of radius 0.2 m rotates freely about its center when a string that is wrapped over its rim is pulled by force

Correct answer

C. A wheel of radius 0.2 m rotates freely about its center when a string that is wrapped over its rim is pulled by force

Step-by-step solution

Cyanide on reduction with DIBAL-H gives aldehyde. Acid halide with rosenmund reduction reaction gives aldehyde. So, all these reaction are correct except benzyl alcohol with oxidation with strong oxidising agents sodium dichromate will give carboxylic acid not the aldehyde.
