Substituen
Dalam kimia organik, substituen adalah atom atau gugus atom yang bersubstitusi menggantikan atom hidrogen pada rantai induk hidrokarbon. Akhiran -il (yang berarti "melekat pada") digunakan dalam penamaan senyawa organik yang mengandung substituen. Selain itu, apabila diperlukan digunakan juga nomor-nomor posisional untuk menandakan atom karbon mana yang bersubstituen. Efek polar yang dihasilkan oleh sebuah substituen merupakan kombinasi efek induktif dan efek mesomerik.
