It has been a week now that my question is remained unanswered i guess the experts are doing their job positively but not in my case the question was asked in my exam of chemistry past weekand and that is why i am eager to know the answer, so here's the quetion whose answer i was looking for.!"A conjugated alkadiene having molecular formula C13H22 on ozonolysis yielded ethyl-methyl ketone and cyclo hexane carbaldehyde.Identify the diene,wite its structural formula and give its IUPAC name"???.
Arrange benzene, n-hexane and ethyne in decreasing order of acidic behaviour. Also give reason for this behaviour.
The addition of HI in the presence of peroxide does not follow anti-markovnikoffs rule becauseA)HI bond is too strong to be broken homolytically.B)reaction of I atom with alkene is endothermic in nature.C)I combines with h to give back HI.d)HI is a reducing agent
