Answer 1

leg double In the reaction the bromine molecule just addred to the El bond tripple bord of the alkyne. Hence the reaction is I addition reaction.] to pH socz ľ In this reaction the olt group is getting substituted with 'ei on. So the reaction is substitution reaction 0 OH - t H2SO4 X + H2O In this reaction one water molecule is getting eliminated from the alcohol and form the alkene. So the reaction is elimination reaction. OH The molecule does not charge molecular formola only from end converted to ketone. So the reaction is rearrangement) • H₂OL Addition reaction / 4 Ⓡoom Condition reaction Ole c oer Resvergement reaction! More than = Elmination reactor. molte Elimination reaction. / KOH 2000
