Silianol (SiH3OH) is more acidic than methanol (CH3OH) why?


We know that acidic strength of an acid also depend upon stability of its conjugate base. So silianol is more acidic than methanol (H3C-OH) because conjugate base silianol (H3Si-OH) stablised by dispersal of negative charge in H3Si-O- ion by 2pπ—3dπ back bonding

Hence methanol is less acidic than silianol.
