Question

Which of the following is not correct about stibanes?

• A. They are formed by the decomposition of $S{b}_2{O}_3$ with $LiAl{H}_4$
• B. They are formed by the decomposition of $SbC{l}_3$ with $NaB{H}_4$
• C. They decompose into Sb and $H_2$ on heating
• D. They are basic in nature

Answer 1

The correct option is D They are basic in nature

Stibanes are $Sb{H}_3$
a) $4S{b}_2{O}_3+6LiAl{H}_4\to 8Sb{H}_3+3L{i}_{2}O+3A{l}_2{O}_3$
b) $4SbC{l}_3+3NaB{H}_4\to 4Sb{H}_3+3NaCl+3BC{l}_3$
c) On heating
$2Sb{H}_3\to 3H_2+2Sb$
d) Due to the large size of the central atom $Sb{H}_3$ does not show basic properties.
