WebAccording to the definition a molecule which can accept a lone pair is called a lewis acid. A) Ammonia has a lone pair on nitrogen,so it can donate the lone pair rather than accepting a lonepair.So,it is a lewis base. B) Water has 2 lone pairs on oxygen so it cannot accept any further lonepairs,so water is a lewis base not a lewis acid.

WebSodium borohydride (or sodium borodeuteride) is also used to convert aldoses or oligosacchrides to alditol derivatives for examination by gas–liquid chromatography–mass spectrometry. Unlike hydride ions, which are electron-rich nucleophiles, diborane is the dimer of an electron-deficient electrophilic species (BH3 ). WebHaving used two electrons in bonding to the terminal hydrogen atoms, each boron has one valence electron remaining for additional bonding. The bridging hydrogen atoms provide one electron each. Thus the B 2H 2 ring is held together by four electrons, an example of 3-center 2-electron bonding. This type of bond is sometimes called a 'banana bond'.
