JEE Mains · Chemistry · STD 11 - 3. Classification of elements and periodicity in properties
Which of these statements is not true
- A \(NO^+\) is isoelectronic with \(O_2\)
- B \(B\) is always covalent in its compounds
- C In aqueous solution, the \(Ti^+\) ion is much more stable than \(Ti (III)\)
- D \(LiAlH_4\) is a versatile reducing agent in organic synthesis
Answer & Solution
Correct Answer
(A) \(NO^+\) is isoelectronic with \(O_2\)
Step-by-step Solution
Detailed explanation
\((a)\, NO^+\, =7+8-1\,=14\,e^-\). \(O_2\, = 16\,e^-\). i.e. not isoelectronic \((b)\) Boron forms only covalent compounds. This is due to its extremely high ionisation energy. \((c)\) Compounds of \(Ti^+\) are much more stable than those of \(Ti^{3+}\). \((d)\, LiAlH_4\) is a…
