Which of the following species is not expected to be a ligand? (a) NO (b) NH4 (c) NH2CH2CH2NH2 (d) Both (a) and (b)

Which of the following species is not expected to be a ligand?

(a) NO

(b) NH4

(c) NH2CH2CH2NH2

(d) Both (a) and (b)

Expert Solution

Answer : (b) NH4

Explanation :

In ammonia, Nitrogen atom has one lone pair of electrons. Nitrogen donates this lone pair of electrons to proton to form ammonium ion. So NH4+ ion does not have a lone pair of electrons which it can donate to central metal ion. Hence it cannot behave as a ligand.

While NO and ethylene diammine are well known ligands. They can donate there electrons to central metal atom.

b) NH4

Chemical species A, B, C, D and E are involved in a reaction. They may represent reactants, products, intermediates, catalysts or inhibitors. The rate of change in the concentration for each of them is given below: d[A]/dt = -k1[A][B] + k-1[C][B] + k2[C][D] - k-2[A][E] d[B]/dt = 0 d[C]/dt = k1[A][B] - k-1[C][B] - k2[C][D] + k-2[A][E] d[D]/dt = -k2[C][D] + k-2[A][E] d[E]/dt = k2[C][D] - k-2[A][E] a) Write down the elementary steps in the proposed reaction mechanism that are...
