9.65 C of 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 Grignard reagent formed is :

A

`5xx10^(-4)`

B

`1xx10^(-4)`

C

`5XX10^(-5)`

D

`1xx10^(-5)`

Text Solution

Verified by Experts

The correct Answer is:
C
(c ) `Mg^(2+)+underset(2F)2e^(-) to underset(1mol)Mg`
`2xx96500" C"` of charge form Mg =1 mol
9.65C of charge form Mg
`=((1mol)xx(9.65" C"))/(2xx(96500" C"))=5xx10^(-5)mol`
`Mg-=RMgX`
Moles of Grignand reagent formed `=5xx10^(-5)mol`.
