A carbon compound A forms B with sodium metal and again A forms C with `PCl_5` , but B and C form diethyl ether. Therefore A, and B and C are
| A. |
`C_2H_5OH, C_2H_5ONa, C_2H_5Cl` |
 |
| B. |
`C_2H_5Cl, C_2H_5ONa, C_2H_5Cl_2` |
| C. |
`C_2H_5OH, C_2H_6, C_2H_5Cl_2` |
| D. |
`C_2H_5OH, C_2H_5Cl, C_2H_5ONa` |
