A reaction between ammonia and boron trifluoride is given below: NH_3 + BF_3 to H_3N :BF_3 Identify the acid and base in the given reaction. Which theory explains it? What is the hybridisation of B and N in the reactants ?

A reaction between ammonia and boron trifluoride is given below: NH_3

1.	A reaction between ammonia and boron trifluoride is given below: NH_3 + BF_3 to H_3N :BF_3 Identify the acid and base in the given reaction. Which theory explains it? What is the hybridisation of B and N in the reactants ?
Answer» <html><body><p></p>Solution :As `BF_3` does not have a <a href="https://interviewquestions.tuteehub.com/tag/proton-1170983" style="font-weight:bold;" target="_blank" title="Click to know more about PROTON">PROTON</a> but acts as <a href="https://interviewquestions.tuteehub.com/tag/lewis-541347" style="font-weight:bold;" target="_blank" title="Click to know more about LEWIS">LEWIS</a> acid as it is an electron deficient molecule. It reacts with `NH_3` by accepting the lone pair of electrons from `NH_3` and <a href="https://interviewquestions.tuteehub.com/tag/complete-423576" style="font-weight:bold;" target="_blank" title="Click to know more about COMPLETE">COMPLETE</a> its octet. The reaction is <br/> `BF+:NH_3 to BF_3 larr NH_3` <br/> Lewis theory of acids and bases can <a href="https://interviewquestions.tuteehub.com/tag/explain-447165" style="font-weight:bold;" target="_blank" title="Click to know more about EXPLAIN">EXPLAIN</a> it. <a href="https://interviewquestions.tuteehub.com/tag/boron-400820" style="font-weight:bold;" target="_blank" title="Click to know more about BORON">BORON</a> in `BF_3` is `sp^2` hybridised where N in `NH_3` is `sp^3` hybridised.</body></html>
