Diborane is molecular hydride
WebMetal hydrides are also known as interstitial hydrides. They are formed when hydrogen molecule reacts with the d- and f-block elements. Metals of group 7, 8, and 9 do not form hydrides. They do conduct heat and electricity but not to the extent of their parent metals. Uses of Hydride. They are used as reducing agents in many chemical industries. 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.
