Options

  1. AAn electron is allowed to move with constant velocity along the axis of current carrying straight solenoid. (A) The
  2. BAn electron is allowed to move with constant velocity along the axis of current carrying straight solenoid. (A) The
  3. CAn electron is allowed to move with constant velocity along the axis of current carrying straight solenoid. (A) The
  4. DAn electron is allowed to move with constant velocity along the axis of current carrying straight solenoid. (A) The

Correct answer

D. An electron is allowed to move with constant velocity along the axis of current carrying straight solenoid. (A) The

Step-by-step solution

In first step bromination reaction will take place. Since hydroxy group on benzene is ortho para directing in nature and aldehyde is meta directing in nature. Bromination will take place at ortho position with respect to hydroxy group and at meta position w.r.t. aldehyde group.

Consider the above reaction sequence, the Product ‘ C ’ is

Next aldehyde will react Hydroxylamine to form oxime. This is an example of nucleophilic addition reaction followed by elimination. In last step dehydration reaction will take place which will convert oxime into cyanide.
