They give white precipitate with tollens reagent not silver mirror precipitate

@rishabhverma6421 4 года назад

@shishirmit 3 года назад

@rishabhverma6421 4 года назад

Sir terminal alkyne and hemiacetal bhi. Yeh test dete hai na sir. Aur sir N2h4 aur Nh2oh kya Hno3 banenge after the rexn

@shishirmit 3 года назад

N2 from hydrazine and hydroxylamine

@shishirmit 3 года назад

Hemiacetals are unstable. So they are irrelevant.

@RishabhJain-ip1vr 4 года назад

Terminal alkyne also give tollen test but do not form silver mirror ,they form red ppt

@kartikgarg441 4 года назад

Why don't we take silver nitrate directly? Wouldn't the complexing make it a weaker oxidising agent

@dasarpv7598 4 года назад

@luvkumar5096 4 года назад

@keshavsingh6053 Год назад

Terminal alkynes give tollens test but not form silver mirror, As we know that tollen's reagent prepared under alkaline conditions, so the media alkaline and due to the presence of alkaline media , it takes the acidic hydrogen from terminal alkynes and form silver acetylides and they are cement-white or white precipates.

@keshavsingh6053 Год назад

So ye kehna sahi hai ki terminal alkynes give tollen's test but it is wrong to say it gives silver mirror test, As sometimes we called tollen's test as silver mirror test but ye kehna galat hai kyunki mostly carbonyl compounds (aldehyde) gives silver mirror on treatment with tollen's reagent but kuch aise compounds bhi jo tollen's ke sath react karke silver mirror nahi banate like jaise terminal alkynes give cement-white ppt . and hydroxyl amines gives grey-black ppt. of silver. So in cases main silver mirror nahi form hota but they give +ve tollen's test but if it is will they give silver mirror with tollen's reagent then our answer is no.
