What are the five shapes of Vsepr?

Molecular Geometries. The VSEPR theory describes five main shapes of simple molecules: linear, trigonal planar, tetrahedral, trigonal bipyramidal, and octahedral.

Is CHF3 ionic or covalent?

Explanation: Each of these molecules is made up of polar covalent bonds; however in order for the molecule itself to be polar, the polarities must not cancel one another out.

Is CHF3 tetrahedral?

The ideal bond angle for the Trifluoromethane is 109.5° since it has a Tetrahedral molecular geometry. …

What is the hybridization of CHF3?

The hybridization the carbon atom in CH3F is sp3. We know this because of the tetrahedral arrangement of atoms around the carbon. The fluorine atom is also sp3 hybridized.

What is the Vsepr shape for sih4?

tetrahedral

How many lone pairs does SiH4 have?

Each hydrogen atom uses its valence electron to pair up with one of the Si valence electrons to form a Si–H bond (four of them in all). there are no valence electrons left over, so the molecule has four bond pairs and no lone pairs.

What are examples of combustible dust?

What are examples of materials that can be a combustible dust hazard?

  • agricultural products such as egg whites, powdered milk, cornstarch, sugar, flour, grain, potato, rice, etc.
  • metals such as aluminum, bronze, magnesium, zinc, etc.
  • chemical dusts such as coal, sulphur, etc.
  • pharmaceuticals.
  • pesticides.
  • rubber.
  • wood.

Does flour explode?

Flour and many other carbohydrates become explosive when they are hanging in the air as dust. Just about any carbohydrate dust, including sugar, pudding mix, fine sawdust, etc., will explode once ignited.

What type of hydride is sih4?

Silane is an inorganic compound with chemical formula, SiH4, making it a group 14 hydride. It is a colourless, pyrophoric, toxic gas with a sharp, repulsive smell, somewhat similar to that of acetic acid.

Where is Silane found?

Occurrence: Silane is not found freely in nature, it should be produced by chemical methods. However, it is possible some hydride of silicon can react in nature to form silane. Physical properties: Silane is a colorless with repulsive odor gas.

How is silane formed?

Silanes have been prepared by the reaction of magnesium silicide (Mg2Si) with acids or by the reduction of silicon chlorides with lithium aluminum hydride. All the silanes burn or explode upon contact with air, and they are decomposed by alkaline solutions with formation of hydrogen and hydrous silica.

What is the structure of silane?
