Passage / Comprehension

In 12 gm of mono basic organic acid, 4.8 gm carbon, 0.8 gm hydrogen and 6.4 gm oxygen present. 0.8 gm of silver salt of same monobasic organic acid left a residue of 0.5175 gm of silver on ignition.

Molecular formula of acid is

Options:

Answer:

Solution:

Sol. ratio

$n_{C} = \frac{4.8}{12} = 0.4 n_{H} = \frac{0.8}{1} = 0.8 n_{O} = \frac{6.4}{16} = 0.4 n = \frac{60}{30} = 2 MF = C_{2} H_{4} O_{2} 121 EF CH_{2} O$
