The formation of the Cl2 molecule can be understood in terms of the sharing of a pair of electrons between the two chlorine atoms, each chlorine atom contributing one electron to the shared pair. Choose the most appropriate name of the bond that is formed
Wurtz reaction is used for the preparation of alkanes from alkyl halides in the presence of sodium and dry ether.For example: CH3Br + 2Na +BrCH3 ---------> CH3CH3 + 2NaBr
Thus two atoms of Na are used.
This is due to the formation of Cu2+ ions in the solution illustrated in following ionic reaction:
Cu(S)+2Ag+(aq)--------------˃Cu2+(aq)+2Ag(s)
Here, Cu is oxidized to Cu2+ (means relasing of 2 electrons from Cu to Cu2+ ) and Ag+ is reduced to Ag(s) (means gaining of 2 electrons from 2Ag+ to 2Ag ) and thus, silver converted into solid state and deposited on copper rod.
