Ques. 1JEE Main 2024, 29 January (Morning Shift)

Given below are two statements : In the light of the above statements, choose the most appropriate from the options given below :

Statement I is false but Statement II is true
Both Statement I and Statement II are true
Both Statement I and Statement II are false
Statement I is true but Statement II is false

Answer

(1) Statement I is false but Statement II is true

Solution

Electronegativity (Pauling): C 2.5, Si 1.8, Ge 1.8, Sn 1.8, Pb 1.9

∵ From Si to Pb the values are almost the same (Pb even slightly higher) ⇒ no gradual decrease ⇒ Statement I is false.

C → non-metal; Si, Ge → metalloids; Sn, Pb → metals ⇒ Statement II is true.

Answer: (1)
