A compound 'X' gives brisk effervescence of \( C O_{2} \) on treatment with Na H \( C O_{3} \) and when treated with Li \( A l H_{4} \) gives ethyl alcohol. Therefore 'X may be:

  • A. \( C H_{3} C O C H_{3} \)
  • B. \( C H_{3} C H_{2} C H O \)
  • C. \( C H_{3} C H O \)
  • D. \( C H_{3} C O O H \)

Step-by-step solution

The brisk effervescence of CO2 with NaHCO3 indicates a carboxylic acid (R-COOH). Reduction with LiAlH4 gives ethyl alcohol (C2H5OH), which is the product of reducing acetic acid (CH3COOH). Other options are aldehydes or ketones and do not react with NaHCO3 to release CO2.
