(i) What is the covalence of nitrogen in N2O5?(ii) BiH3 is a stronger

1.	(i) What is the covalence of nitrogen in N2O5?(ii) BiH3 is a stronger reducing agent than SbH3, why?
Answer» (i) 4 (ii) Due to lower bond dissociation enthalph of BiH₃as compared to SbH₃. Detailed Answer: (ii) Because BiH₃has longer bond length due to larger size of Bi it has lowest bond dissociation energy which makes it less stable than SbH_3.
