Options
- A. A
- B. B
- C. C
- D. D
Answer
A. A
Step-by-step solution
Hexamethylene diamine series give (+) carbylamine test. C _ x H _ y N _ z +(2 x +1 / 2) CuO xCO _2+ y 2 H _2 O + z 2 ~N _2 (Dumas method) C _6 H _ 16 ~N _2 then z 2 ~N _2= 2 2 ~N _2=1 mole Given 10 mole in this reaction so w _ N _2 =10 28=280 gm
