Question

Match List-I with List-II:

List-I	List-II
(A) Linus Pauling	(iii) Electronegativity
(B) Albert Einstein	(ii) Photoelectric effect
(C) Ernest Rutherford	(i) Alpha particle scattering experiment
(D) Max Planck	(iv) Black body radiations

Choose the correct answer from the options given below:

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

Hint:

Linus Pauling defined electronegativity which is the ability to attract electrons in a covalent bond; Albert Einstein explained the photoelectric effect, which demonstrates the particle nature of light; Ernest Rutherford discovered the atomic nucleus by alpha scat- tering; Max Planck proposed quantized energy of black body radiation.

Answer 1

The Correct Option is A

Scientists with their major scientific contributions:
• Linus Pauling = concept of electronegativity
• Albert Einstein = photoelectric effect
• Ernest Rutherford = alpha particle scattering experiment
• Max Planck = quantum theory of black body radiation
The correct answer is: (A) - (iii), (B) - (ii), (C) - (i), (D) - (iv).
