(i) XeF2 has linear structure and not a bent structure.

Hint— No. Bending will be different in different liquids since velocity of light at the interface separating two media depends on the relative refractive index of the medium.

[Hint : Due to presence of 2LP and 3BP.]

[Hint : In XeF2, 2 bond pairs and 3 lone pairs are present hence linear structure.]

[Hint : (i) 2XeF2 (s) + 2H2O (l) → 2Xe (g) + 4HF (aq + O2 (g) (ii) Xe + PtF6→ Xe+[PtF6]-]

NeF2 does not exist.

Elbow and knee are not made up of a single bone, but two or more bones which are joined to each other by a joint (Hinge joint). This joint along...

 the number of lone pairs on Xe are respectively  (d) 3, 2, 1.

(c) Hybridisation of XeF2 is sp3d
