Equal moles of hydrogen and oxygen gases are placed in a container with a pin-hole through which both can escape. How many moles of Oxygen gas escape in the time required for half a mole of the hydrogen to escape?
The thionyl chloride method is preferred over hydrogen chloride or phosphorous chloride method for the preparation of haloalkanes because both the by-products (SO2 and HCl) in this case are gases and escape leaving behind pure chloroalkane. This reaction takes place in the presence of
