Identify the correct statements: i. Oxidation of NaBH ₄ with I ₂ gives B ₂ H ₆ ii. B ₂ H ₆ burns in oxygen and releases an enormous amount of energy iii. B ₂ H ₆ on hydrolysis gives a tribasic acid

Step-by-step solution

(i) 2 NaBH ₄+ I ₂ ~B ₂ H ₆+2 NaI + H ₂ (ii) B ₂ H ₆+3 O ₂ ~B ₂ O ₃+3 H ₂ O + Energy (iii) B ₂ H ₆( ~g )+6 H ₂ O 2 ~B ( OH )₃+6 H ₂ B ( OH )₃+ H ₂ O B ( OH )₄⁻+ H ⁺ B ( OH )₃ is a monobasic acid.
