- (d) Vitamin B₁ and Vitamin B₆
Answer and solution
Answer (d) Vitamin B₁ and Vitamin B₆
Solution
Chemistry ma’am · 3 steps
Match each chemical name to its vitamin: thiamine is B1, pyridoxine is B6. The order matters too.
- Recall the names. The B vitamins and vitamin E each have a chemical name. This question tests whether you can match those names to the right label.
Chemical name Vitamin Deficiency disease Thiamine B₁ Beriberi Riboflavin B₂ Cheilosis (cracked lips and mouth corners) Pyridoxine B₆ Convulsions Tocopherol E Fragile red blood cells, muscular weakness - Check the order. The question says "respectively", so the first vitamin must belong to thiamine and the second to pyridoxine.
- So. Thiamine is vitamin B₁ and pyridoxine is vitamin B₆, in that order. The answer is (d).
The idea to keep. Learn the B vitamins as name, number and deficiency together: thiamine B₁ (beriberi), riboflavin B₂ (cheilosis), pyridoxine B₆ (convulsions). Tocopherol is vitamin E.
