Which of the following statement is false?

Options

  1. AChlorophyll is responsible for the synthesis of carbohydrate in plants
  2. BIn presence of oxygen, haemoglobin forms oxyhaemoglobin
  3. CAcetyl salicylic acid is known as aspirin
  4. DVitamin B ₁₂ contains Mg ²⁺ ion

Correct answer

D. Vitamin B ₁₂ contains Mg ²⁺ ion

Step-by-step solution

Chlorophyll is responsible for the synthesis of glucose (carbohydrate) in plants. In presence of oxygen, haemoglobin forms oxyhemoglobin. Acetyl salicylic acid is known as aspirin Vitamin B ₁₂ (Cyanocobalamin, C ₆₃ H ₈₈ O ₄ ~N ₁₄ PCo ) contains Co ²⁺ ion.
