In Tollen,s test for aldehyde, the overall number of electron(s) transferred to the Tollen's reagent formula `[Ag(NH_(3_(2)))]^(+)` per aldehyde group to form silver mirror is....... (Round off to the Nearest Integer).

Text Solution

Verified by Experts

The correct Answer is:
2
`RCHO + 2[Ag(NH_3)_2]^(+) + 3HO^(-) rarr RCOO^(-) + 2Ag + 2H_2O + 4NH_3`
For 1mol of R-CHO, 2 mol of `[Ag(NH_3)_2]^(+)` is reduced.
`2[Ag(NH_3)_2]^(+) + 2e^(-) rarr 2Ag + 2NH_3`
