Use the following to answer Questions 6-8:
An unknown organic compound \( X \) has a relative molecular mass of 180. It is a colourless crystalline solid, readily soluble in water. X contains the elements \( \mathrm{C}, \mathrm{H}, \) and \( O \) in the atomic ratio \( 1: 2: 1 \). The compound has a sweet taste and melts on heating. In the presence of yeast and in the absence of air, \( X \) is converted to compound \( Y \) and a colourless gas. Compound \( Y \) reacts with sodium metal to produce a gas \( Z \). which gives a 'pop' sound with a glowing splint. \( Y \) also reacts with ethanoic acid to give a sweet smelling compound W.
The molecular formula of X is

D.
\( \mathrm{C}_{2} \mathrm{H}_{14} \mathrm{~A}_{7} \)
E.
\( \mathrm{C}_{4} \mathrm{H}_{8} \mathrm{~A}_{4} \)
Correct Answer
B
Correct Option:
\( \mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6} \)
