Tertiary carbocations are more stable than secondary. C 5 H 12. Identify the functional group.

When the chain cannot include the C C a substituent name is used. Dehydrohalogenation of this compound gives two alkenes. C 3 H 10 N 2.

However a substance classified in category 2 may be used in cosmetic products where the substance has been evaluated by the SCCS and found safe for use in cosmetic products. The suffix -ene means that this compound is an alkene and there must be a double bond in the molecule. Contrairement aux aldéhydes qui nont autour de ce groupement quun carbone primaire cest un carbone secondaire lié à exactement 2 atomes de carbone voisins qui porte le groupement carbonyle pour les cétones.
