{\text{Li}_{3} \text{N}\text{+}{H}_{2} \text{O} \to \text{A} \left(\text{gas}\right)<br />{\text{Li} }_{2} {\text{CO}}_{3} \overset{Δ}{→} B(gas)\text{B} \left(\text{gas}\right)
Hybridisation of the central atom in AandB\text{A} and \text{B} respectively.$$Li_ 3 N+ H _ 2 O → A (gas) Li _ 2 CO _ 3 Δ → B (gas) Hybridisation of the central atom in A and B respectively.Li_ 3 N+ H _ 2 O → A (gas) Li _ 2 CO _ 3 Δ → B (gas) Hybridisation of the central atom in A and B respectively.

Options

  1. A\text{s}{\textp^{3}\text{, sp}
  2. B\text{s}{\textp^{2}\text{, s}{\textp^{3}
  3. Csp,spsp, sp
  4. D\text{s}{\textp^{3}\text{, s}{\textp^{3}

Correct answer

A. \text{s}{\textp^{3}\text{, sp}

Step-by-step solution

Li3N+3H2O→3LiOH+NH3L{i}_{3}N + 3{H}_{2}O \to 3LiOH + N{H}_{3}

Li_ 3 N+ H _ 2 O → A (gas) Li _ 2 CO _ 3 Δ → B (gas) Hybridisation of the central atom in A and B respectively.

Li2CO3→ΔLi2O+CO2L{i}_{2}C{O}_{3}\overset{\Delta}{→}L{i}_{2}O + C{O}_{2}

Li_ 3 N+ H _ 2 O → A (gas) Li _ 2 CO _ 3 Δ → B (gas) Hybridisation of the central atom in A and B respectively.
