Question

Which of the following oxidation states are the most characteristics for lead and tin respectively?

• A. +4, +2
• B. +2, +4
• C. +4, +4
• D. +2, +2

Answer 1

The correct option is B +2, +4

Lead and tin are in the fourth group of the periodic table,so we can expect an oxidation state of +4 for both of them.But due to the reluctance of participation of electrons in the outermost s orbital in bonding i.e., inert pair effect which increases down the group.So, the oxidation states of lead and tin are +2 and +4 respectively which is also evident from their respective chemical reactions
