Explain.............1) allyl
2) vinyl
3) allene
4) vicinal.

Answer:

Allyl group:Allyl group holds three carbon atoms and five hydrogen atoms.

An allyl group is a substituent with the structural formula H2C=CH−CH2R, where R is the rest of the molecule

Vinyl:Vinylgroup has two carbon atoms and three hydrogen atoms

Allene:A molecule having two carbon-carbon double bonds that share a single sp carbon. Also refers to propadiene (H2C=C=CH2), the parent member of this series

Vicinal:describes any two functional groups bonded to two adjacent carbon atoms
