An organic compound $A(C6H6O)A\left({C}_{6}{H}_{6}O\right) gives dark green colouration with ferric chloride. On treatment with CHCl3{CHCl}_{3} and KOH,KOH, followed by acidification gives compound B.B . Compound BB can also be obtained from compound CC on reaction with pyridinium chlorochromate (PCC). Identify A,BA, B and $C .An organic compound A( C _ 6 H _ 6 O) gives dark green colouration with ferric chloride. On treatment with CHCl _ 3 andAn organic compound A( C _ 6 H _ 6 O) gives dark green colouration with ferric chloride.

Options

  1. AHow many values of the magnetic orbital quantum number (m l ) are possible for a subshell with l = 1?
  2. BHow many values of the magnetic orbital quantum number (m l ) are possible for a subshell with l = 1?
  3. CHow many values of the magnetic orbital quantum number (m l ) are possible for a subshell with l = 1?
  4. DHow many values of the magnetic orbital quantum number (m l ) are possible for a subshell with l = 1?

Correct answer

A. How many values of the magnetic orbital quantum number (m l ) are possible for a subshell with l = 1?

Step-by-step solution

The reaction with ferric chloride is test for phenol. The reaction of AA with CHCl3andKOH{CHCl}_{3}andKOH to give BB is Riemer-Tiemann reaction. The conversion CtoBC\text{to}B is an oxidation reaction.
