Answer: d-orbitals account for the sulphur- oxygen double bond.
Explanation:
Looking at the nature of bonding in SOCl2, the sulphur is bonded to two chlorine atoms and one oxygen atom. The sulphur has a lone pair of electrons. There are four bonds and four electron pairs if we don't count the lone pair on sulphur. This leads to a tetrahedral shape. However, if we invoke a valence state in which d orbitals are involved and the thionyl chloride is still sp3 hybridized, then we will have one electron in the d-orbital which overlaps with a 2p electron from oxygen to form the double bond. The four sp3 orbitals accommodate eight electrons including the lone pair on sulphur while the d-orbital accommodates the remaining two electrons from the pi-bond thereby completing the ten electrons.

Explanation:
The given data is as follows.
= 250 mL,
= 750 mL
=
= 35 + 273 K = 308 K
= 35 + 273 K = 308 K
= 0.55 atm,
= 1.5 atm
P = ? , V = 10.0 L
Since, temperature is constant.
So, = PV
Now, putting the given values into the above formula as follows.
= PV
=
P = 0.126 atm
As, 1 atm = 760 torr. So, = 95.76 torr.
Thus, we can conclude that the final pressure, in torr, of the mixture is 95.76 torr.
