Which of the following& statements is false ?

Which of the following& statements is false ?

Options

  1. ALiAlH4 is versatile reducing agent in organic synthesis.
  2. BNO+ is not isoelectronic& with O2
  3. CB is always covalent in its compounds
  4. DIn aqueous solution, the Tl+ ion is much more stable than Tl (III)

Correct answer

C. B is always covalent in its compounds

Step-by-step solution

(i) LiAlH4& is a versatile reducing agent
(ii) NO+ (14 electrons), O2(16 electrons) not isoelectronic
(iii) Tl+ is more stable due to Inert pair effect
(iv) B compounds are ionic as well&

B2O3+2NaOH→2NaBO2+H2O{B}_{2} {O}_{3} + 2 NaOH \to 2 {NaBO}_{2} + {H}_{2} \text{O}&
