Question

choose correct option.which of the following shows most prominent inert pair effect? a.C b.Si c.Ge d.Pb​

Answer 1

Answer:

d.Pb

Explanation:

Answer 2

Lead (Pb) shows the most prominent inert pair effect among the following given elements.

• Inert pair effect is the unavailability of the outermost s-elctrons to participate in bonding.
• This takes place because of the electrons in s-orbitals being closer to the nucleus are attracted strongly by the nucleus, which does not allow them to participate in bonding.
• As we go down a group in the periodic table , the effective nuclear charge increases hence, lead being located at the bottom of the group shows most prominent inert pair effect.
