The false statement among the following is:

In the Carius method of estimation of halogen, 0.172g of an organic compound showed the presence of 0.08g of bromine. The correct structure of the compound among the following is:

1.		2.	\(\mathrm{H}_3 \mathrm{C}-\mathrm{CH}_2-\mathrm{Br} \)
3.		4.	\(\mathrm{H}_3 \mathrm{C}-\mathrm{Br}\)

The Kjeldahl method of Nitrogen estimation fails for which of the following reaction products?

3.		4.

1.  (a), (c) and (d)
2.  (b) and (c)
3.  (a) and (d)
4.  (c) and (d)

In an estimation of bromine by the Carius method, 1.6 g of an organic compound gave 1.88 g of AgBr. The mass percentage of bromine in the compound is: 

[Atomic mass, Ag=108, Br = 80 g ${\mathrm{mol}}^{-1}$]

1. 50 %
2. 55.5%
3. 60 %
4. 70 %

Match the following:

1. (i)-(d). (ii)-(c), (iii)-(e), (iv)-(a)

2. (i)-(b), (ii)-(d), (iii)-(e), (iv)-(a)

3. (i)-(d), (ii)-(c), (iii)-(b), (iv)-(e)

4. (i)-(b), (ii)-(a), (iii)-(c), (iv)-(d)

An organic compound 'A' is oxidized with Na₂O₂ followed by boiling with HNO₃. The resultant solution is then treated with ammonium molybdate to yield a yellow precipitate. Based on the above observation, the element present in the given compound is:

1.  Fluorine

2.  Phosphorus

3.  Nitrogen

4.  Sulphur
