Chemistry Question 70 – JEE-MAIN 2025

← Back
Fat soluble vitamins are: A. Vitamin B1 B. Vitamin C C. Vitamin E D. Vitamin B12 E. Vitamin K Choose the correct answer from the options given below:

Vitamins are essential organic compounds classified based on their solubility in either fat or water.

Ninja Strategy•Recall Basic Vitamin Solubility

Knowing the fundamental classification of vitamins into fat-soluble (ADEK) and water-soluble (B-complex, C) allows for quick elimination of incorrect options.

Step 1: Recall Vitamin Solubility Classification✦ Active

Vitamins are classified into two main groups based on their solubility: fat-soluble and water-soluble.

Fat-soluble vitamins include Vitamins A, D, E, and K.

Water-soluble vitamins include the B-complex vitamins (e.g., B1, B12) and Vitamin C.

💡 Teacher's Secret Hint

Remember the mnemonic 'ADEK' for fat-soluble vitamins.

Step 2: Identify Fat-Soluble Vitamins from the List○ Expand

From the given list of vitamins:

A. Vitamin B1 is water-soluble.

B. Vitamin C is water-soluble.

C. Vitamin E is fat-soluble.

D. Vitamin B12 is water-soluble.

E. Vitamin K is fat-soluble.

Therefore, the fat-soluble vitamins from the list are Vitamin E and Vitamin K.

Step 3: Match with the Given Options○ Expand

We need to find the option that correctly lists Vitamin E and Vitamin K.

Option 1: A & B Only (B1 and C are water-soluble).

Option 2: B & C Only (C is water-soluble, E is fat-soluble).

Option 3: C & E Only (Vitamin E and Vitamin K are both fat-soluble).

Option 4: C & D Only (E is fat-soluble, B12 is water-soluble).

Thus, option 3, 'C & E Only', correctly identifies the fat-soluble vitamins from the given list.
