Question

Which of the following sequence of $T$ and $F$ is correct for given statements? Here $T$ stands for the true and $F$ stands for false statement.
(i) The tendency to show $+2$ oxidation state increase in the sequence $Ge<Sn<Pb$.
(ii) Tin in $+2$ state is a reducing agent.
(iii) Lead compounds in $+2$ state are strong oxidising agents.
(iv) In tetravalent state molecules of group $14$ elements act as electron donor species.

• A. TTTT
• B. TTFF
• C. TTFT
• D. TFFT

Answer 1

Answer: (B)

Lead compounds in $+4$ state are strong oxidising agents. In tetravalent state the number of electrons around the central atom in a molecule is eight. Being electron precise molecules, they are normally not expected to act as electron acceptor or electron donor species.
