Question

An organic compound A contains 48.6% Carbon, 8.1% Hydrogen, and the remaining being Oxygen when reacted with ethanol in the presence of tetraopesulphate (w) acid. The resulting compound was a fragrant smelling legend B with a relative molecular mass of 102. What is compound A?

a) Acetone
b) Acetic Acid
c) Ethanol
d) Ethyl Acetate

Answer 1

The compound A with the given composition of 48.6% Carbon, 8.1% Hydrogen, and the remaining being Oxygen is acetic acid, which has the empirical formula CH₂O.

Step-by-step explanation:

The compound A with the given composition of 48.6% Carbon, 8.1% Hydrogen, and the remaining being Oxygen is acetic acid, which is also known as vinegar. The molecular formula for acetic acid is C₂H₄O₂, indicating that it contains two carbon atoms, four hydrogen atoms, and two oxygen atoms. The simplest, whole-number ratio of these atoms is 1:2:1, giving the empirical formula CH₂O.
