To calculate the lambda max in the UV spectrum of a compound, we need to consider the functional groups present in the compound and their corresponding absorption wavelengths.

Without knowing the specific compound, it is difficult to provide an exact value for the lambda max. However, we can make some general predictions based on common functional groups:

- Aromatic compounds typically absorb in the range of 200-300 nm, with a lambda max around 250 nm.
- Conjugated systems, such as double bonds or aromatic rings, can shift the lambda max to longer wavelengths.
- Functional groups like carbonyl groups (C=O) typically absorb around 200-300 nm, with a lambda max around 280 nm.

If you provide the specific compound or more information about its structure, we can give a more accurate prediction of the lambda max in its UV spectrum.

The lambda max (λmax) of a compound is the wavelength of light at which it absorbs the most light. It is a characteristic property of each compound and can be used to identify it.

The lambda max of 2-methyl-1-butene is 210 nm. This is in the ultraviolet (UV) region of the spectrum.

The UV spectrum of 2-methyl-1-butene is shown below. The lambda max is the peak of the absorption curve.

The lambda max of a compound is affected by several factors, including the structure of the molecule, the solvent in which it is dissolved, and the temperature.

The structure of the molecule is the most important factor in determining the lambda max. Compounds with conjugated double bonds have a lower lambda max than compounds with isolated double bonds. This is because the conjugated double bonds allow the electrons to delocalize, which makes the molecule more stable.

The solvent in which the compound is dissolved can also affect the lambda max. Solvents that are polar can interact with the compound and cause the lambda max to shift to a higher wavelength.

The temperature can also affect the lambda max. As the temperature increases, the lambda max will shift to a higher wavelength.
