A phenyl group is formed when one atom of hydrogen is removed from the ring structure of the benzene. In this way, the molecular structure turns from C6H6 to C6H5. The hydrogen removed can be replaced by a number of elements and compounds. The phenyl group, therefore, belongs to the class of organic compounds which are aromatic in nature.
The phenyl group has a hexagonal planar structure and the length of the bonds between all the carbon atoms remains the same and it is 1.4 angstrom. The phenyl group is hydrophobic and is an electron-withdrawing group.
