How many 2C 2e bonds are in b2h6?
Four 2C-2e bonds
Four 2C-2e bonds and four 3C-2e bonds. Hint: Diborane is a chemical compound that consists of boron and hydrogen atoms.
What is the point group of pcl5?
PCl5 contains a C3 main rotation axis and 3 perpendicular C2 axes. There are 3 σv planes and a σh plane. Hence PCl5 belongs to the D3h point group.
Is HOCl symmetrical?
HOCl. Hypochlorous acid possesses a single mirror plane only. The point-group symmetry for this molecule is given the crystallographic symbol m.
What is the point group of NOCl?
Simple symmetries: we begin the list of table with two point groups that are found when molecules with minimal symmetry are considered. For example, the bent molecule NOCl has only a plane of symmetry and the staggered molecule H2O has only a C 2 axis of symmetry. Each, of course, has the identity symmetry element.
How many BHB 3C 4e bonds are there in B2H6?
two 2C−2e bonds and four 3C−2e bonds.
How is B2H6 a 3C 2e bond?
A B−H−B 3-center-2-electron bond is formed when a boron atom shares electrons with a B−H bond on another boron atom. In diborane (B2H6), there are two such 3c-2e bonds: two H atoms bridge the two B atoms, leaving two additional H atoms in ordinary B−H bonds on each B.
What is symmetry of PCl5?

What is the reaction between diborane and oxygen?
As a pyrophoric substance, diborane reacts exothermically with oxygen to form boron trioxide and water: Diborane reacts violently with water to form hydrogen and boric acid : Diborane also reacts with alcohols similarly. Methanol for example give hydrogen and trimethylborate:
Is diborane electron deficient or electron deficient?
Traditionally, diborane has often been described as electron-deficient, because the 12 valence electrons can only form 6 conventional 2-centre 2-electron bonds, which are insufficient to join all 8 atoms.
How is diborane prepared from hydride donors?
Most preparations entail reactions of hydride donors with boron halides or alkoxides. The industrial synthesis of diborane involves the reduction of BF 3 by sodium hydride, lithium hydride or lithium aluminium hydride:
