Compound ‘Y’ (molar mass = 88.12 g mol –1 ) containing 54.52% carbon, 9.17% hydrogen and 36.31% oxygen gives a reddish-brown precipitate in Fehling’s test. ‘Y’ is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
Assume 100 g of the compound is present
C ⇒ 54.52 g ⇒ 4.5 moles
H ⇒ 9.17 g ⇒ 9.17 moles
O ⇒ 36.31 g ⇒ 2.2 moles
So, empirical formula = C 2 H 4 O
Only α -Hydroxy ketones gives fehling solution test.
So, 
is correct answer .
(M.F. = C 4 H 8 O 2 )
