MCQ
Holme signal can be given by the using
- A$CaC_2 + CaCN_2$
- ✓$CaC_2 + Ca_3P_2$
- C$CaC_2 + CaCO_3$
- D$Ca_3P_2 + CaCN_2$
✓
Answer
Correct option: B.
$CaC_2 + Ca_3P_2$
b
$\text{Ca}{{\text{C}}_{2}}+\text{C}{{\text{a}}_{3}}{{\text{P}}_{2}}\xrightarrow{{{H}_{2}}O}$ ${\text{Ca}}{({\text{OH}})_2} + \mathop {\boxed{{{\text{C}}_2}{{\text{H}}_2} + {\text{P}}{{\text{H}}_3}}}\limits^{Signal} $
$\text{Ca}{{\text{C}}_{2}}+\text{C}{{\text{a}}_{3}}{{\text{P}}_{2}}\xrightarrow{{{H}_{2}}O}$ ${\text{Ca}}{({\text{OH}})_2} + \mathop {\boxed{{{\text{C}}_2}{{\text{H}}_2} + {\text{P}}{{\text{H}}_3}}}\limits^{Signal} $
