Define bond order and give the relationship between bond order and bond length
Bond order (b.o.) is defined as one half the difference between the number of electrons present in the bonding and the antibonding orbitals i.e., Bond order (b.o.) = ½ (Nb–Na) Bond...

Is the bond energy of all the four C-H bonds in CH4 molecule equal? If not then why ? How is C-H bond energy then reported?
No because after breaking of C-H bonds one by one, the electronic environments change. The reported value is the average of of the bond dissociation energies of the four C-H...

Why is Group V of qualitative analysis, sufficient NH4 OH solution be added before adding (NH4)2 CO3 solution?
This is done to convert NH4 HCO3 usually present in large amounts along with (NH4)2 CO3 to (NH4) 2 Co3 NH4 HCO3 +NH4OH_------> (NH4 )CO3 H2O
