Highly selective Backlog Qs for JEE MainChemistryClassification of Elements and Periodicity in Properties
Among Me ₃ N , C ₅ H ₅ N and MeCN (Me = methyl group) the electronegativity of N is in the order
Options
- AMeCN > C _ g H _ s N > Me ₃ N
- BC ₃ H ₅ N > Me ₃ N > MeCN
- CMe ₃ N > MeCN > C ₃ H _ s N
- DElectronegativity same in all
Correct answer
A. MeCN > C _ g H _ s N > Me ₃ N
Step-by-step solution
In Me ₃ N N is s p³ -hybrid and in MeCN N is s p -hybrid Also electronegativity of any element %s -character in hybrid orbitals. Thus, order of electronegativity for nitrogen is MeCN > C ₅ H ₅ N < Me ₃ N
