For each compound, select all that apply conjugated non conjugated diene trine conjugated non conjugated diene triene conjugated non conjugated diene triene conjugated non conjugated diene triene

1.Two carbon–carbon multiple bonds are separated by one carbon–carbon single bond. So, it is a conjugated compound.

1.Explanation | Common mistakes | Hint for next step

The given compound contains one carbon–carbon double bond and one carbon–carbon triple bond; those are separated by one carbon–carbon single bond. Therefore, it is a conjugated compound.

2.Three carbon–carbon double bonds are found in the above compound, which is having alternating carbon–carbon single and double bonds. So, it is a conjugated triene.

2.Explanation | Common mistakes | Hint for next step

The given compound contains three alternating carbon–carbon double bonds. Therefore, it is a conjugated triene.

3.

The triple bonds are separated by more than one carbon–carbon single bonds. Therefore, it is non-conjugated.

3.Explanation | Common mistakes | Hint for next step

The given compound is non-conjugated in which carbon–carbon triple bonds are separated by two carbon (sp3 hybridized) atoms.

4.

One carbon–carbon double and one carbon–oxygen double bonds are separated by one carbon– carbon single bond. Therefore, it is conjugated.

4.

Explanation | Common mistakes

The above given compound contains one carbon–carbon double and one carbon–oxygen double bonds; both bonds are separated by one carbon–carbon single bond. Therefore, it is a conjugated compound.
