Answer:

The naphthalene molecule is fully planner which means all the atoms are in the same plane. Thus, it is following the fourth criteria as well. Thus, a naphthalene molecule is following all the essential criteria of Huckel's rule. Hence, according to Huckel's rule of aromaticity, naphthalene is an aromatic compound.

Answer:

In order to determine whether a compound is aromatic or not in terms of Huckel’s rule, let us look at the postulates of Huckel’s rule of aromaticity.

According to the Huckel’s rule of aromaticity, the basic criteria for a compound to be aromatic are:

(1) The molecule must be a cyclic molecule (the molecule must have a ring system).

(2) The molecule must possess (4n+2) number of π electrons (where n is zero or any positive integer number).

(3) The molecule must have a fully conjugated system (all the atoms in the ring must be sp2 hybridized). All the π electrons must be fully delocalized in the ring system.

(4) The molecule must be planner at all costs (all the atoms in the ring system must be in the same plane).

If a cyclic compound follows the above criteria, then the molecule is said to be an aromatic molecule.

Now, naphthalene is the simplest bicyclic aromatic compound having the molecular formula C10H8. A naphthalene molecule consists of two benzene rings and they are fused together. The basic structure of a naphthalene molecule is given below:

Now, let’s judge where all the postulates of Huckel’s rule apply to naphthalene or not.

-First of all, a naphthalene molecule is a cyclic molecule which means it has a ring system (a naphthalene molecule has two benzene rings fused together). Hence, it is following the first criteria.

-The molecule is having a total of 10 π electrons in the ring system. Hence, it is following the second criteria (4n+2 electrons, where n=2).

-All the π electrons are fully delocalized in the ring system of a naphthalene molecule. It is having a fully conjugated system with all the carbon atoms sp2 hybridized. Hence, it is also following the third criteria.

-The naphthalene molecule is fully planner which means all the atoms are in the same plane. Thus, it is following the fourth criteria as well.

Thus, a naphthalene molecule is following all the essential criteria of Huckel’s rule. Hence, according to Huckel's rule of aromaticity, naphthalene is an aromatic compound.

option b is the right answer

Answer:

Generally, short-term credit is defined as a bank loan with a maturity of less than a year, while long-term credit is a loan repayable beyond a year without a provision for rollover.

Explanation:

Hope this helps you thanku ｡◕‿◕｡

Short-term and long-term credit differs mainly in the time for which these are borrowed.

Explanation:

1. Short-term credit refers to the form of credit which is borrowed for a shorter duration.
2. The short-term credit is generally borrowed for financing the regular needs of a firm such as payment of wages, payment of bills, etc.
3. Long-term credit refers to the credit which is borrowed for a longer duration.
4. Long-term credit is generally used for financing heavy activities such as borrowing machinery, borrowing land, etc.
