protonolysis of organoborane is done by acetic acid...but same thing can't be done mineral acid like hcl h2so4 ..why
usually basic oxygen portion of acetic acid cordinate with boron . helping to increase the acidity of hydrogen to liberate more.....if that so same thing can also occur by hcl..where cl- cordinate with boron and thae alkyl group breaks and capture the hydrogen proton...but it won't occur???
