How do you nomenclature naphthalene?

How do you nomenclature naphthalene?

As an aromatic hydrocarbon, naphthalene’s structure consists of a fused pair of benzene rings….Naphthalene.

How many lines will naphthalene anion show?

7 Naphthalene Anion Radical. This radical anion consists of one unpaired electron interacting with two sets (α and β) of four equivalent protons each as shown in Fig. 4.12. The ESR spectrum would thus show, i.e., (2nI1 + 1) × (2nI2 + 1) = (4 + 1) × (4 + 1) = 25 lines.

What are the rules in naming aromatic compounds?

According to IUPAC nomenclature of substituted aromatic compounds, the substituent name is placed as a prefix to the name of aromatic compounds. For example, a benzene ring attached to a one-nitro group is named as nitrobenzene.

What are the steps to naming an aromatic compounds?

In general, to name an aromatic compound, you can follow these steps:

1. Identify and name the parent.
2. Identify and name the substituents.
3. Number the ring to give the substituents the smallest possible number.
4. Put the substituents alphabetically followed by the parent name.

Do substituents affect aromaticity?

It has been shown that the less aromatic the system, the stronger the substituent influence on its π-electron structure. In all cases, when the substituent changes number of π-electrons in the ring in the direction of 4N+2, its aromaticity increases.

Is naphthalene aromatic or nonaromatic?

5)Naphthalene shows substitution reactions with electrophiles rather than addition reactions , just as benzene. All the above points clearly indicate that naphthalene is an aromatic entity too. It is not as aromatic as benzene, but it is aromatic nonetheless.

Is naphthalene planar or planar?

1)Naphthalene is planar .Naphthalene has two rings fused together with 10 carbon atoms. All the carbon atoms are sp2 hybridized. This molecule has 10 p-orbitals over which can overlap. Thus , the electrons can be delocalized over both the rings.

What is naphthalene used for?

Naphthalene (91-20-3) is a component of crude oil and is found in petroleum-derived fuels and consumer products. The most common use of naphthalene in consumer products is in the production of mothballs.

Why is benzene more stable than naphthalene?

So, for naphthalene , the resonance energy per ring = 63 ÷2 = 31.5 kcal/mol, which is less than that pf benzene. Thus, benzene is more stable than naphthalene. Technically , n aphthalene has fused rings unlike benzene and thus the two systems are different and cannot be compared.
