What is a heteroatom group?

The key difference between heteroatom and functional group is that a heteroatom is any atom other than carbon and hydrogen, whereas functional group is an atom or a group of atoms that is responsible for the chemical reactivity of an organic compound.

What functional groups contain heteroatoms?

Heteroatom Functional Groups In contrast, halide, alcohol, ether, thiol, sulfide, and amine functional groups, which are comprised of only single bonds, each contain a specific heteroatom, as shown below in Figure 10.9. 2.

What are Kekule structures?

Kekulé was the first to suggest a sensible structure for benzene. The carbons are arranged in a hexagon, and he suggested alternating double and single bonds between them. Each carbon atom has a hydrogen attached to it. This diagram is often simplified by leaving out all the carbon and hydrogen atoms!

What is condensed formula in chemistry?

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.

Which elements are heteroatoms?

Typical heteroatoms are nitrogen (N), oxygen (O), sulfur (S), phosphorus (P), chlorine (Cl), bromine (Br), and iodine (I), as well as the metals lithium (Li) and magnesium (Mg).

What are heteroatoms with examples?

Heteroatom is any atom other than carbon and hydrogen. Examples: Nitrogen, sulphur, chlorine and bromine are heteroatoms. The name and formula of two organic compounds containing different heteroatoms are (i) chloromethane, CH3Cl, and (ii) formaldehyde HCHO.

Why is Kekulé structure wrong?

In benzene, all of the carbon-carbon bond lengths are equal. Therefore, the Kekule structure shown below is an incorrect representation of benzene. It is incorrect because it suggests that there are two different types of carbon-carbon bonds in benzene, a carbon-carbon double bond and a carbon-carbon single bond.

What is condensed structure?

What is a 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.

How do you write compounds in condensed form?

To write the condensed structural formula, or semi-structural formula:

  1. Step 1: Draw the 2-dimensional structural formula for the molecule.
  2. Step 2: Identify the carbon backbone (or skeleton) and any branches or side-chains in the structural formula as well as any functional groups such as halogen (group 17) atoms.

How many heteroatoms are present?

In the given structure there are two heteroatoms present namely: oxygen and nitrogen. Likewise , we can identify heteroatoms on the basis of the molecular formula also. Note:The polarity between carbon and oxygen bonds depends on the electron attracting properties of these atoms.
