H3PO3 undergoes disproportionation rxn because in this Phosphorous is present in +3 oxidation state which is not stable so it changes into H3PO4 and PH3 but in H3PO4 Phosphorous is present in +5 oxidation state which is stable so it doesn't undergoes disproportionation reaction.

AlCl3 as Lewis acid

Avantika Tayal 6 years, 1 month ago

The reagent i.e anhydrous alcl3 make a salt complex with nh2 on the benzene ring and makes it deactivated and so no freidal craft alkylation or acylation takes place...same would happen if cooh grp would have present instead of nh2...

Tamanna Sharma 6 years, 1 month ago

Because the reagent used AlCl3 acts as a lewis base ,here and attack on the lone pair of the N present in aniline and precipitate out and further reaction is not proceed

Ranitidine n cimetidine r antacids as well as antihistamine because these were designed to prevent the interaction of histamine with receptors present in the stomach walls n u know that histamine is responsible for the production of pepsin n HCl in stomach. Hence these also control hyperacidity.

Avantika Tayal 6 years, 1 month ago

Ranitidine is a antihistamine which works as a antacid(ncert mein likha hai) it has same effect as that of antacid the only difference is its receptors are different and so is considered somewhat different from antacid....

Tamanna Sharma 6 years, 1 month ago

It's , ok even my chemistry teacher not clear my confusion and internet is also showing rantidine as both on different -different sites.

Shruti Jha 6 years, 1 month ago

I donno if am right but this is what i have learnt!

Shruti Jha 6 years, 1 month ago

Ranitidine is in a group of drugs called histamine-2 blockers. Ranitidine works by reducing the amount of acid your stomach produces. Brompheniramine is an antihistamine that reduces the effects of natural chemical histamine in the body. ... So Ranitidine and Cimetidine are antihistamine antacids.
