JEE Main levelOne or more correct optionsDifficulty 2 of 3pb100

Which of the following statements about compounds of tin are correct?

A $SnCl X_{4}$ is a covalent liquid that fumes in moist air.
B $SnCl X_{2}$ is a good oxidising agent and is not easily oxidised.
C $Sn (OH) X_{2}$ is amphoteric.
DAqueous $SnCl X_{2}$ reduces $HgCl X_{2}$ .

Answer: A, C, D

SnCl X_{4}

is a covalent, volatile liquid that hydrolyses and fumes in moist air.

SnCl X_{2}

is a reducing agent because Sn(IV) is the more stable state, so the second statement is false.

Sn (OH) X_{2}

dissolves in both acids and alkalis.

SnCl X_{2}

reduces

HgCl X_{2}

to

Hg X_{2} Cl X_{2}

and Hg. Statements 1, 3 and 4 are correct.
