Chemical Bonding And Molecular Structure Question 421
Question: Which of these statements is not true-
Options:
A) $ N{O^{+}} $ is not isoelectronic with $ O_2 $
B) B is always covalent in its compounds
C) In aqueous solution, the $ T{l^{+}} $ ion is much more stable than Tl (III)
D) $ LiAlH_4 $ is a versatile reducing agent in organic synthesis.
Show Answer
Answer:
Correct Answer: A
Solution:
- $ N{O^{+}}=7+8-1=14{e^{-}}. $ $ O_2=16{e^{-}}~ $ i.e not iso-electronic
[b] Boron forms only covalent compounds. This is due to its extremely high ionization energy
[c] Compounds of $ T{l^{+}} $ are much more stable than those of $ T{l^{3+}} $
[d] $ LiAlH_4 $ is a versatile reducing agent in organic synthesis
