What is condensed structural formula?
A condensed structural formula is a system of writing organic structures in a line of text. It shows all atoms, but omits the vertical bonds and most or all the horizontal single bonds. The condensed structural formulas of ethane, propane, and ethanol are. CH₃CH₃, CH₃CH₂CH₃, and CH₃CH₂OH.
What is the condensed structural formula of an alkane with 4 carbons?
An alkane is a hydrocarbon in which there are only single covalent bonds. The simplest alkane is methane, with the molecular formula CH4. The carbon is the central atom and makes four single covalent bonds to hydrogen atoms.

What is the molecular structure of CH4?
The molecular geometry of CH4 is Tetrahedral. The carbon (C) central atom is located in the center of the tetrahedron, while the four hydrogens (H) atoms are located on the vertices. These atoms repel each other in a way that the final shape of CH4 appears like Tetrahedral.

Condensed Formula Examples
The molecular formula lists the number and type of atoms but gives no indication of the bonds between them. The condensed formula is CH3(CH2)4CH3. Although less commonly used, the condensed formula of hexane could also be written as CH3CH2CH2CH2CH2CH3.

How do you write a condensed structural formula for an alkene?
It is named using the same stem as the alkane having the same number of carbon atoms but ends in -ene to identify it as an alkene. Thus the compound CH2=CHCH3 is propene.

What is the shape geometry in CH4?
For example; four electron pairs are distributed in a tetrahedral shape. If these are all bond pairs the molecular geometry is tetrahedral (e.g. CH4).
Why is CH4 a tetrahedral shape?
CH4 Molecular Geometry
According to VSEPR theory, electron pairs of the same nature repel each other. There are four bonding pairs of electrons, so to keep their repulsive forces at a minimum, they take the tetrahedral molecular geometry. Hence, CH4 or Methane has a Tetrahedral Molecular geometry.

Which of the following is an example of a condensed formula of an alkane?
What is a condensed structural formula give an example?
For instance, the condensed structural formula of methane is CH4 and propanol is CH3 (CH2)2OH. Thus, we can say that in condensed structural formula, every carbon atom is signified individually. Moreover, the following carbon atoms are positioned to the atoms which bond to that specific carbon atom.
Is CH4 trigonal planar?
Four electron pairs arrange themselves in space in what is called tetrahedral arrangement. A tetrahedron is a regular triangularly-based pyramid.
What is the shape of CH4? (a) Pyramidal. (b) Trigonal planar. (c) Linear. (d) Tetrahedral.

Is CH4 tetrahedral or square planar?
Hence, CH4 is tetrahedral in shape.

How do you condense a formula?
What do you mean by condensed formula?
The condensed formula of a molecule is the formula where the symbols of atoms are listed in order as they appear in the molecule’s structure with bond dashes omitted or limited. While vertical bonds are always omitted, sometimes horizontal bonds are included to indicate polyatomic groups.
What is the shape of CH4?
tetrahedral shape
For example; four electron pairs are distributed in a tetrahedral shape. If these are all bond pairs the molecular geometry is tetrahedral (e.g. CH4).
Why is CH4 not square planar 11?
For square planar geometry, the hybridisation has to be \[ds{p^2}\]. But in methane, there is no involvement of d-orbitals as it has less electrons. So, it cannot have square planar geometry.
Is CH4 a tetrahedral?
It turns out that methane is tetrahedral, with 4 equal bond angles of 109.5° and 4 equal bond lengths, and no dipole moment.
