Question

during liebigs method 1 g of organic compound is found to form 0.9 of water .the percentage of h in organic compound is​

Answer 1

Answer:

..

Explanation:

Correct option is

C

C=52.17%;H=13.04% and O=34.79%

Increase in the mass of U-tube =1.08 g

Mass of water formed =1.08 g

Since, 18 g of water contains 2 g of hydrogen.

1.08 g of water contains

18

2

×1.08 g of hydrogen.

Mass of the compound taken for analysis =0.92 g

Percentage of hydrogen =

18

2

×

0.92

1.08

××100=13.04

Increase in the mass of potash bulbs =1.76 g

Mass of carbon dioxide formed =1.76 g

Since, 44 g of carbon dioxide contains 12 g carbon.

1.76 g of carbon dioxide contains =

44

12

×1.76 g carbon.

Percentage of carbon =

44

12

×

0.92

1.76

×100=52.17

Percentage of oxygen =100−(percentage of C + percentage of H)

=100−(52.17+13.04)

=100−65.21=34.79

Composition of the compound: C=52.17%;H=13.04% and O=34.79%
