A, B, C, D, e, F, G, spice, nonane, decane to express, the number of carbon atoms in more than 11, with digital representation.Oil of paraffin and isoparaffin.Normal alkanes in paraffin base oil in high content; isoparaffin in asphaltic base oil in high content.Alkane called alkyl groups [ 1].Alkane molecular formula formula for CnH2n+2, where "n" indicates the number of carbon atoms in molecules."2n+2" indicates the number of hydrogen atoms.At normal temperature and normal pressure, C1-C4 Deadidasjeremyscottt.com alkane gaseous, present in; C5-C15 alkane is liquid, oil is the main component; more than C16 Adidas Jeremy Scott Wings alkane is solid.Two.As the name suggests it is a cyclic structure.The most common is five carbon atoms and six carbon Adidas Jeremy Scott atoms of the ring, the former is cyclopentane, the latter name.Naphthenic hydrocarbon molecular formula formula for CnH2n.Naphthenic hydrocarbon | |
