JEE MAIN - Chemistry (2024 - 29th January Morning Shift - No. 6)
Given below are two statements :
Statement I : The electronegativity of group 14 elements from $$\mathrm{Si}$$ to $$\mathrm{Pb}$$, gradually decreases.
Statement II : Group 14 contains non-metallic, metallic, as well as metalloid elements.
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
Explanation
$$\begin{array}{ll} \text { Gr-14 } & \text { EN } \\ \mathrm{C} & 2.5 \\ \mathrm{Si} & 1.8 \\ \mathrm{Ge} & 1.8 \\ \mathrm{Sn} & 1.8 \\ \mathrm{~Pb} & 1.9 \end{array}$$
The electronegativity values for elements from $$\mathrm{Si}$$ to $$\mathrm{Pb}$$ are almost same. So Statement $$\mathrm{I}$$ is false.
