My school you people have done so much
🙇B is actually correct because of the triple bond and also every one here shouldn't complain because only -yne- and carbon (II) oxide are the only substance which react with ammoniacal copper (I) chloride
The question is wrongly composed:
the answer should be B, because it is only alkyne members that give a precipitate with ammonical copper (1) chloride.
REF: Check newschool chemistry under the test for alkyne
the the answer is wrng. it's the triple bonds only dt forms yellow ppt wif ammonicl coppr [1] chloride. and, dt's wat diffrnt8s double triple bnds frn double bnds!
MYSCHOOL.COM.NG you pipo should check yo answers well and not tell me something i can swear on dat tiz wrong
I don't tink d and is there,bcos we know alkyne has triple bond however it also has a general 4mula of CnH2n-2
@myschool.com.ng, you guys should try to give us correct answer,don't make people dislike your website.the correct answer is B, only Alkyne series will give a precipitate with ammoniacal solution
The correct answer should be B. It is the Alkyne series that precipitate ammoniacal copper(1)chloride not Alkene. In fact, if C is the correct answer, then, A and D are also correct because A,C,D belong to the same series(Alkene)
