Which of the following statements is false ?

Options

  1. ALiAlH 4 is versatile reducing agent in organic synthesis.
  2. BNO + is not isoelectronic with O 2
  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) LiAlH 4 is a versatile reducing agent (ii) NO + (14 electrons), O 2 (16 electrons) not isoelectronic (iii) ​Tl + is more stable due to Inert pair effect (iv) B compounds are ionic as well B 2 O 3 + 2 NaOH → 2 NaBO 2 + H 2 O (Sodium meta Borate)
