Bingel [31]

At its discovery, benzene was recognized to be a unique unsaturated hydrocarbon because it either failed to react, by substitution with common reagents or reacted by addition that led to reactions with alkenes.

<h3>What are unsaturated hydrocarbons?</h3>

Unsaturated hydrocarbons are the hydrocarbons which have at least on double or triple carbon to carbon bond in its molecules.

All other hydrocarbons are unsaturated except for the alkanes and the cyclic alkanes.

Benzene is an aromatic compound which has a special six-carbon ring with are resonance structure reflecting the presence of three carbon-carbon bonds in its molecules.

The common reactions of unsaturated hydrocarbons are substitution and addition reactions.

However, benzene on its discovery did not undergo any of these reactions.

In conclusion, benzene showed a difference when compared with the common unsaturated hydrocarbons as it did not undergo either substitution or addition reactions.

How many grams of Helium can be found in 3.4 moles of it.
MaRussiya [10]

one mole

If we look this number up for helium, we find that helium has a molar mass of 4.0 grams per mole. So one mole of helium has a mass of 4.0 grams. We can use the molar mass as a conversion factor. Two moles of helium times four grams of helium per mole of helium is equal to eight grams of helium.
