A) \[{{C}_{5}}{{H}_{8}}N\]
B) \[{{C}_{10}}{{H}_{12}}N\]
C) \[{{C}_{5}}{{H}_{7}}N\]
D) \[{{C}_{10}}{{H}_{14}}N\]
Correct Answer: C
Solution :
| [c] Relative number of atoms, |
| For \[C=\frac{74}{12}=6.1,\] |
| For \[H=\frac{8.65}{1}=8.65,\,\,\] |
| For \[N=\frac{17.3}{14}=1.2\] |
| Simplest ratio: |
| For \[C=\frac{6.1}{1.2}=5,H=\frac{8.65}{1.2}=7,\,N=\frac{1.2}{1.2}=1;\] |
| Hence, empirical formula \[={{C}_{5}}{{H}_{7}}N\] |
