Please write down the structural formula of benzene homologues conforming to c9h12~ 8 Kinds ~
Answer: The six carbon atoms on the benzene ring are represented by 1,2,3,4,5,6, if the other three carbon atoms are connected to one carbon atom, there are two forms, such as in the case of No.1 carbon atom, straight chain, and the other is branched chain, if the other three carbon atoms are in the form of a methyl group and an ethyl group, there are three forms: adjacent, such as methyl group in No.1.
How many isomers of C9H12 are homologues of benzene?
There are three kinds of methyl groups: three adjacent sites, two adjacent sites, one interphase site and three interphase sites.
There are three kinds of 1 ethyl 1 methyl: adjacent, interphase and para - position.
There's only one propyl, just put it anywhere.
To sum up:7 kinds in total.
