The group 14 elements A and B have the first ionisation enthalpy values of 708 and 715 kJ mol respectively. The above values are lowest among their group members. The nature of their ions  and  respectively is

Canvas Classes · Accepted Answer

Step 1: Identify elements A and B

Group 14 elements: C, Si, Ge, Sn, Pb

First ionisation enthalpies (kJ/mol): C(1086)  Si(786)  Ge(762)  Sn(708)  Pb(715)

The two lowest IE values in Group 14 are Sn (708) and Pb (715).

So: A = Sn (IE = 708), B = Pb (IE = 715)

Step 2: Analyse  =

can be oxidised to  (loses 2 more electrons) → acts as a reducing agent

(reducing)

Step 3: Analyse  =

tends to gain electrons to form more stable  → acts as an oxidising agent

(oxidising)

Answer: (c) reduci
