Question

Test to distinguish between alkyne and terminal alkyne?

Answer 1

) ammonical silver nitrate test ------> with ammonical silver nitrate solution (tollens reagent) alkyne gives a white precipitate but alkene does not

for example :-

ethyne + tollens reagent --------> silver acetylide (white ppt) + NH3 + H2O

ethene + tollens reagent ---------> no reaction

(ii)ammonical cuprous chloride test ----------> with an ammonical cuprous chloride , alkyne gives a red precipitate while alkene does not react

for example -

ethyne + ammonical cuprous chloride -------->copper acetylide (red ppt) + NH3 + H2O

ethene + ammonical cuprous chloride ----------> no reactio

Answer 2

Explanation:

alkynes these have at least one carbon tribal bond along with single bonds their general formula is CN h2n -2 organic compounds with same molecular formula but structural formula and COD isomers the phenomena is called ISO marriage made the functional group such as alcohol LD heights and carboxylic acids decide characteristics properties of the carbon compound that are contained them
