The base value of this structure is 253 nm. There are 4 alkyl substituents which add a value of 20 (4x5 nm). So the lambda max of this structure is 273 nm.
This is because these substituents have too many interferences.

Substituents with a positive Hammet substituent constant are electron withdrawing. Examples include CF3.
There are a number of cellular substituents which are produced in the nucleus. Some of them include ribosomes, genes, nucleoli and so many more.
an example of Alkyl halides is R-X ( x represents any halogen) C2F4 is Teflon it is an example of Alkyl Halides
Substituents with a negative Hammet substituent constant are electron donating. Examples include R groups and OH groups.
it is C6H5-R , R = any alkyl group.
Depending on the desired definition of the word "contaminant" Alkyl Benzene Sulfonate is more likely the answer. Linear Alkyl Sulfonates are far more readily biodegraded than Alkyl Benzene Sulfonate due to their relative chemical structures. Alkyl Benzene Sulfonate can cause issues in waterways such as eutrophication, which in turn can lead to algal blooms.
the synthesis of alkyl fluorides by heating an alkyl chloride or alkyl bromide in the presence of a metallic fluoride like AgF, Hg2F2, CoF2 or SbF2.
An alkyl phosphate is any ester derived from an aliphatic alcohol and phosphoric acid.
When one hydrogen is removed from an alkane it forms alkyl group
