- $ CaO+N_{2} $
- $ CaC+N_{2} $
- $ CaC_{2}+N $
- $ CaC_{2}+N_{2} $
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Nitrolim' is prepared by heating finely powdered $CaC _{2}$ with a little of $CaCl _{2}$ in the atmosphere of $N _{2}$ at $1000-1100^{\circ} C$, in an electric furnace
$CaC _{2}+ N _{2} {->[{1000-1100^{\circ} C }][{\left( CaCl _{2}\right)}]}\underset{\text{nitrolim}}{\left[ CaCN _{2}+ C \right]}$

Concepts Used:
Group 2 Elements
The group two or alkaline earth metals are s-block elements with two electrons in their s-orbital. They are alkaline earth metals. They are named so because of the alkaline nature of the hydroxides and oxides.
Alkaline earth metals are characterized by two s-electrons. This group of elements includes:
- Beryllium (Be)
- Magnesium (Mg)
- Calcium (Ca)
- Strontium (Sr)
- Barium (Ba)
- Radium (Ra)
Elements whose atoms have their s-subshell filled with their two valence electrons are called alkaline earth metals. Their general electronic configuration is [Noble gas] ns2. They occupy the second column of the periodic table and so-called as group two metals also.
