All the following alkenes give the same product either in hydroboration oxidation (or) in acidic hydration except.

1, 3, 4 are symmetrical alkenes. Whether Markonikoff addition of water (acidic hydration) (or) anti Markoni koff's addition of water (hydroboration- oxidation) give same product.(2)  A) CH3-CCH3|=CH2→H3O+CH3-CCH3|OH|-CH3       B) CH3-CCH3|=CH2→b) H2O2/OH-a) B2H6/THFCH3-CCH3|H|-COH|H2
