Question

Consider the following two reactions : Cd^2+ (aq.) + 4CH3NH2 $\rightarrow$ 'A', \Delta G^\circ_1 ; Cd^2+ (aq.) + 2H2NCH2CH2NH2 $\rightarrow$ 'B', \Delta G^\circ_2 . According to given information the correct statement(s) is/are :

Prashant Kotian · Accepted Answer

Correct answer: A,B,D. Step 1: Identify that CN^-, CO, and NO^+ are 14-electron isoelectronic species (CN^- = 6+7+1 = 14; CO = 6+8 = 14; NO^+ = 7+8-1 = 14). Step 2: According to molecular orbital (MO) theory, any 14-electron diatomic species has a bond order of 3.0 with all electrons paired in the molecular orbitals. Step 3: Consequently, all three species are diamagnetic and possess a bond order of three, matching option (a).
