9.65 C electric current is passed through fused anhydrous magnesium chloride. The magnesium metal thus obtained is completely converted into a Grignard reagent. The number of moles of the grignard reagent obtained is

Answer»

`5xx10^(-4)`
`1xx10^(-4)`
`5xx10^(-5)`
`1xx10^(-5)`

SOLUTION :`MG^(2+)+2e^(-)toMg`
2F, i.e., `2xx96500C` deposit Mg=1mole
`therefore9.65C` will deposit Mg
`=(1)/(2xx96500)xx9.65=5xx10^(-5)` MOLE
`RX xx MgtoRMgX`
1 mole of Mg forms G.R.=1 mole
`therefore5xx10^(-5)` of Mg will FORM G.R.
`=5xx10^(-5)` mole.
