The propene reacts with $HBr$ to form

Addition of $HBr$ to propene in the presence of a peroxide takes place contrary to Markovnikov rule. This can be explained by the mechanism involving

The conversion of $2,3-$dibromobutane to $2-$butene using $Zn$ and alcohol is a/an .... reaction.

Which type of bond exists between the two carbon atoms of an alkene?

Which of the following alkenes on oxidation by $KMnO_4$ in dil. $H_2SO_4$ forms adipic acid?

$A$ benzene derivative did not produce a white precipitate with ammoniacal silver nitrate solution (Tollens' reagent) but decolorized cold dilute alkaline $KMnO_4$ solution (Baeyer's reagent). The compound is:
