Rohan was given three unknown organic compounds `P, Q` and `R`. To identify the compounds, he tested the compounds with different reagents and noted down his observations in the given table.

Compounds `P, Q` and `R` are respectively

Options

A. Methane, methanol and methyl methanoate
B. Ethanoic acid, soap solution and ethanol
C. Ethanoic acid, ethyl ethanoate and ethanol
D. Methane, methanal and methanoic acid.

Answer

B

Explanation

Compound P :
`CH_(3)COOH + NaHCO_(3) to CH_(3)COONa +H_(2)O +CO_(2)`
`CH_(3)COOH + Na to CH_(3)COONa +1//2H_(2)`
Compound R:
`CH_(3)CH_(2)OH +Na to CH_(3)CH_(2)ON a +1//2H_(2)`
Compound Q:
Soaps are basic in nature as they are sodium salts of higher fatty acids hence, they turn red litmus blue.
