How many types of nomenclature in the features of organic chemistry? What are they?
12345 [234]

Answer:

there are two types of nomenclature used in organic system. the most widely used and universally accepted system of nomenclature is the IUPAC system of nomenclature. some compounds are referred to by their common name that existed before the IUPAC system or is more widely known than the IUPAC names.

Explanation:

IUPAC ( international union of pure and applied chemistry) system of nomenclature is used to name compounds in organic system. there are some principles to be followed while using this nomenclature. some of them are:-

1) identification of parent chain is the first step. the longest hydrocarbon chain is the parent chain.

2) identification of all the substituent groups of the parent chain is also required.

3) hydrocarbon cyclic ring has a fixed prefix and  that is cyclo.

For the following reaction in aqueous solution, identify all those species that will be spectator ions. Select all that apply.
FromTheMoon [43]

The reaction is incorrect. The correct reaction is: Na₂SO₄ + Hg(NO₃)₂ → HgSO₄ + 2NaNO₃. The options are:

A. Hg₂SO₄

B. Na₂SO₄

C. Na⁺

D. NO₃⁻

E. SO₄⁻²

F. Hg₂(NO₃)₂

G. NaNO₃

H. Hg⁺²

Answer:

C, D, E, H

Explanation:

The ions are formed after dissociation of the compound in the solution. When they're negatively charged, they're called anions, when they're negatively charged, they're called cations. If the ion is presented on both sides of the reaction, it is called a spectator ion.

Thus, the reaction given:

Na₂SO₄ + Hg(NO₃)₂ → HgSO₄ + 2NaNO₃

So, let's do the dissociation.

Na₂SO₄ is formed by the ions Na⁺ and SO₄⁻²;

Hg(NO₃)₂ is formed by the ions Hg⁺² and NO₃⁻;

HgSO₄ is formed by the ions Hg⁺² and SO₄⁻²;

NaNO₃ is formed by the ions Na⁺ and NO₃⁻.

Thus, the spectator ions are Na⁺, SO₄⁻², Hg⁺², and NO₃⁻.
