Explain why terminal alkynes give an aldehyde when the reagent
is BH3 / H2O2/NaOH but methyl ketones when the reagent is Hg2+and
H3O+,
Na/NH3 A reagent that gives a stereoselective product ( i.e. a
trans alkene isomer)
Lindlar catalyst A reagent that gives a stereoselective product
( i.e. a cis alkene isomer)
Explain why terminal alkynes ( pKa ~ 25 ) are much more acidic
than terminal alkenes ( pKa ~ 44)
Given a ketone or aldehyde write the corresponding...
