What descriptive term is applied to the type of diene represented by 2,4-hexadiene?.
Varvara68 [4.7K]

The descriptive term applied to the type of diene represented by 2,4-hexadiene is conjugated diene.

Dienes are compounds which contains two double bonds. These dienes can be non conjugated or conjugated.

Conjugated diene are those compound which have two double bonds  joined by a single σ bond. Conjugated dienes can also be called 1,3-diene. To know if diene is conjugated or non conjugated, sp³ hybridization is to b checked and the number of double bonds and single sigma bond is checked.

Conjugated dienes are found in many different molecules. 2,4-hexadiene is a conjugated diene with two carbon-carbon double bonds that are separated by one sigma bond.

The stabilization of dienes by conjugation is better than the aromatic stabilization. Conjugated dienes are more stable than non conjugated or cumulative diene because it has higher electron density of molecules delocalized.

To learn more about conjugated dienes,

The  experimental value of Avogadro's number will be ±0.050.

<h3>What is the degree of accuracy?</h3>

The degree of accuracy refers to the extent to which a measurement is correct. Now we know that the measurement obtained by an instrument is as correct as its degree of accuracy.

Hence, given that the margin of error is about 0.050, the  experimental value of Avogadro's number will be ±0.050.

Ne4ueva [31]
I've done this a few times and keep coming up with 5.0 L . I used the mole ratio, and SO 2 as the LR. That would make 2 moles of SO3 5.0 L but its not one of your choices. the temp and pressure are constant, so according to n/v = p/rt the volume is the same as the moles. hope this helps
