2-Bromobutane + alc. KOH --------2-Butene(A) +Br2 ------- 2,3 dibromobutane(B) + alc. KOH ----- 2-Butyne + H2O, Hg2+/H2SO4---- 2- Butanone
The reactions are as follows:
CH3−CH2−CHBr−CH3 + alc. KOH →CH3−CH=CH−CH3 2−Bromobutane 2−Butene (A)CH3−CH=CH−CH3 + Br2 → CH3−CHBr−CHBr−CH3 (A) 2,3 dibromobutane (B)CH3−CHBr−CHBr−CH3 + alc.KOH →CH3−C≡C−CH3 (B) 2−Butyne (C)CH3−C≡C−CH3 +H2O −→−−H2SO4Hg2+ CH3COCH2CH3 (C) 2−Butanone
The reactions are as follows:
CH3−CH2−CHBr−CH3 + alc. KOH →CH3−CH=CH−CH3 2−Bromobutane 2−Butene (A)CH3−CH=CH−CH3 + Br2 → CH3−CHBr−CHBr−CH3 (A) 2,3 dibromobutane (B)CH3−CHBr−CHBr−CH3 + alc.KOH →CH3−C≡C−CH3 (B) 2−Butyne (C)CH3−C≡C−CH3 +H2O −→−−H2SO4Hg2+ CH3COCH2CH3 (C) 2−Butanone
