AIIMS Chemistry Mock Test - 2 - Question 8

Which of the following gas changes lime water in milky colour?

AIIMS Chemistry Mock Test - 2 - Question 9

The pair of species having identical shapes for melecules of both species is

Detailed Solution for AIIMS Chemistry Mock Test - 2 - Question 9
Correct option(b) XeF2,CO2
Explanation:
XeF2 contains sp3d hybridised Xe atom with three lone pairs of electrons. Fluorine atoms occupy axial positions while three lone pairs of electrons occupy equatorial positions in trigonal bipyramid. Since the lone pair of electrons does not consider for the shape of the molecule, thus, the shape of XeF2 comes out to be linear. While C -atom of CO2 is sp hybridised and thus, possesses a linear shape.
