stephen's reduction of cyanide

[static quartz]

The CN should be converted into aldehyde?

the Sn + HCl rxn

Note for OP

+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.

[elfin pelican]

nah nah

it will turn into CH2NH3

additon of H occurs from Sn + HCL

it is correclty written in the paper

[fallow kiln]

Hydrogen gets added na.

Where does o come from

[elfin pelican]

reduction me hi to h add hoga na

[elfin pelican]

Huh?

[static quartz]

ye wali rxn nhi hogi?

[fallow kiln]

I think there is a hydrolysis step

Metallic Sn is a stronger reducing agent

[fallow kiln]

I don't think that's true. Do you have a source for this?

every step of reduction involves the transfer of 2 electrons

To NO2 to NH2, Sn is transferred from 0 to +4 oxidation state

only 1 equivalent gets used up entirely and CN remains untouched, and if not mentioned, the 'intended' step is reduction of nitro group

[static quartz]

What if reagent is in excess

[finite citrus]

Then there maybe chances of stephen's reduction

I would reccomend looking up mechanism for Sn HCl reduction

and see other sources

standard books

[static quartz]

If moles aren't given then we assume that in excess

[static quartz]

SnCl2 HCl is normally given in Books. Sn HCl i searched on Google there is no reduction with it.

[finite citrus]

mechanism bhejo phir

[static quartz]

Sn HCl ki nhi hae

[static quartz]

Ye rhi Stephen's reduction ☝️

[static quartz]

Ye banega na

[fallow kiln]

Hi

Source is a book yes :)

[fallow kiln]

I think sn2+ is the std state.

thank you sir
