Question

Match List I with List II:

List I	Functional Group	List II Description
A	Hydroxyl	I. DNA
B	Carboxyl	II. Proteins
C	Amino	III. Polar
D	Phosphate	IV. Fatty acids

Choose the correct answer from the options given below:

• (A) - (III), (B) - (IV), (C) - (II), (D) - (I)
• (A) - (I), (B) - (II), (C) - (III), (D) - (IV)
• (A) - (II), (B) - (IV), (C) - (I), (D) - (III)
• (A) - (IV), (B) - (III), (C) - (I), (D) - (II)

Hint:

Remember the key associations: Hydroxyl (polar), Carboxyl (fatty acids), Amino (proteins), and Phosphate (DNA).

Answer 1

The Correct Option is A

- Hydroxyl (A - III): Hydroxyl groups exhibit high polarity due to oxygen's electronegativity.
- Carboxyl (B - IV): Carboxyl groups are primary components of fatty acids.
- Amino (C - II): Amino groups are found in amino acids, the building blocks of proteins.
- Phosphate (D - I): Phosphate groups form the structural backbone of DNA molecules.
