Consider the following statements about group 13 elements A. \(\mathrm{AlCl}_3\) gets stability by forming a dinner B. \(\mathrm{BCl}_3\) is an electron deficient molecule C. \(\mathrm{E}_{\mathrm{M}^{3+}{ }_{\mathrm{M}}^0}^0(\mathrm{~V})\) is +1.26 for aluminium D. In +1 oxidation state thallium is unstable The incorrect statements are
- A C and D only
- B A and B only
- C A and D only
- D B and C only
Answer & Solution
Correct Answer
(A) C and D only
Step-by-step Solution
Detailed explanation
\(\mathrm{AlCl}_3\) gets stability by forming a dimer due to availability of \(\mathrm{d}\) orbital, \(\mathrm{BCl}_3\) is an \(\mathrm{e}^{-}\)deficient molecule because the outermost orbit shows only \(6 \mathrm{e}^{-}\)after bonding with \(\mathrm{Cl}\) atom. Hence it get…
