What is Alkyl Group?
An alkyl group is a substituent derived from an alkane by removing one hydrogen atom. The general formula is CₙH₂ₙ₊₁– (or R–). Common alkyl groups include methyl (–CH₃), ethyl (–C₂H₅), propyl (–C₃H₇), and butyl (–C₄H₉). Alkyl groups are electron-donating substituents in organic chemistry and are named by replacing the -ane suffix of the parent alkane with -yl.

No hazard from the concept itself. Specific alkyl-containing compounds vary widely in hazard — alkyl halides are often toxic and potentially carcinogenic.
