Question

Lime stone is an ore of Calcium. On decomposition gives an oxide (A)
and $C{O}_2$ gas. ‘A’ is reduced by Coke to give ‘B’ and Volatile gas.
$B+N_2\underset{{1200}^{\circ }C}{\overset{CaC{l}_2}{\to }}Nitrolim$
Nitrolim is a fertilizer.
The type of bonds present in compound (B) are:

• A. Ionic only
• B. Both Ionic & Covalent
• C. Dative bond
• D. Ionic, Covalent & dative

Answer 1

The correct option is B Both Ionic & Covalent

Lime stone is an ore of Calcium. On decomposition gives an oxide (A)
and $C{O}_2$ gas. ‘A’ is reduced by Coke to give ‘B’ and Volatile gas.
$B+N_2\underset{{1200}^{\circ }C}{\overset{CaC{l}_2}{\to }}Nitrolim$
Nitrolim is a fertilizer.
‘B’ is $Ca{C}_2$
