Question

(a) Complete the following chemical reaction equations
(i) $P_4+S{O}_{2}C{l}_2\to$
(ii) $Xe{F}_6+H_{2}O\to$
(b) Predict the shape and the asked angle (${90}^o$ or more or less) in each of the following cases :
(i) $S{O}_3^{2-}$ and the angle $O-S-O$
(ii) $Cl{F}_3$ and the angle $F-Cl-F$
(iii) $Xe{F}_2$ and the angle $F-Xe-F$

Answer 1

(a) - (i) $P_4+10S{O}_{2}C{l}_2\to 4PC{l}_5+10S{O}_2$

(ii) Equation for complete hydrolysis:

$Xe{F}_6+H_{2}O\to Xe{O}_3+6HF$

Equations for partial hydrolysis

$Xe{F}_6+H_{2}O\to XeO{F}_4+2HF$

$Xe{F}_6+2H_{2}O\to Xe{O}_2{F}_2+4HF$

(b) (i) Shape: Pyramidal (ref. image 1)

Angle $O-S-O$: More than ${90}^o$

(ii) Shape : T-shaped (ref. image 2)

Angle $F-Cl-F$ : Less than ${90}^o$

(iii) Shape : linear (ref. image 3)

Angle $F-Xe-F$ : ${180}^o$
