Sia ? 6 years, 6 months ago

Propyne is CH3-C=-CH 
CH3-C=CH + Hg2+ + H2O {tex}\rightarrow{/tex} CH3-CO-CH3 
CH3-CO-CH3 + LiAlH4 {tex}\rightarrow{/tex} CH3-CH(OH)-CH3 (2-propanol) 
CH3-CH(OH)-CH3 + H2SO4 + H2O {tex}\rightarrow{/tex} CH3-CH=CH2 (propene) 
CH3-CH=CH2 + BH3 + H2O2/OH- {tex}\rightarrow{/tex} CH3-CH2-CH2OH 
This is hydroboration oxidation 
CH3-CH2-CH2OH  + PCC {tex}\rightarrow{/tex} CH3-CH2-CHO (propanal)
