An organic compound 'AA' (C9H10O)\left({C}_{9}{H}_{10}O\right) when treated with conc. HIHI undergoes cleavage to yield compound 'BB' and 'CC'. 'BB' gives yellow precipitate with {\text{AgNO}_{3} where as 'CC' tautomerizes to 'DD'. 'DD' gives positive iodoform test. 'AA' could be:An organic compound ' A ' ( C _ 9 H _ 10 O) when treated with conc. HI undergoes cleavage to yield compound ' B ' and 'An organic compound ' A ' ( C _ 9 H _ 10 O) when treated with conc. HI undergoes cleavage to yield compound ' B ' and 'An organic compound ' A ' ( C _ 9 H _ 10 O) when treated with conc. HI undergoes cleavage to yield compound ' B ' and 'An organic compound ' A ' ( C _ 9 H _ 10 O) when treated with conc. HI undergoes cleavage to yield compound ' B ' and 'An organic compound ' A ' ( C _ 9 H _ 10 O) when treated with conc. HI undergoes cleavage to yield compound ' B ' and '

Options

  1. AMatch the following: Column - I Column - II (a) Transverse wave through a steel rod (i) B + ((4)/(3))(η)/(ρ) (b)
  2. BMatch the following: Column - I Column - II (a) Transverse wave through a steel rod (i) B + ((4)/(3))(η)/(ρ) (b)
  3. CMatch the following: Column - I Column - II (a) Transverse wave through a steel rod (i) B + ((4)/(3))(η)/(ρ) (b)
  4. DMatch the following: Column - I Column - II (a) Transverse wave through a steel rod (i) B + ((4)/(3))(η)/(ρ) (b)

Correct answer

C. Match the following: Column - I Column - II (a) Transverse wave through a steel rod (i) B + ((4)/(3))(η)/(ρ) (b)

Step-by-step solution

Benzene ring should not be attached to O atom otherwise it will yield phenol after reacting withHIHI so third option is prefect which gives benzyl iodide and it gives yellow precipitate of AgIAgI after reacting with AgNO3{AgNO}_{3}. Another product tautomerises and gives acetaldehyde which gives iodoform test.
