Three isomers of C2HfClBr are possible.
C3H4O can have two isomers: propynal and cyclopropanone.
There are a total of three structural isomers of C7H16 that have no secondary hydrogen atoms. These isomers are 2-methylhexane, 3-methylhexane, and 2,2-dimethylpentane.
There are three isomers of C3H6I2: 1,1-diiodopropane, 1,2-diiodopropane, and 2,2-diiodopropane.
I'm unable to draw images, but I can describe the isomers of heptyne for you. Heptyne has two possible isomers: 1-heptyne and 2-heptyne. 1-heptyne has the triple bond on the first carbon, while 2-heptyne has the triple bond on the second carbon.
The molecule that shows 3-heptyne is heptyne. It has a triple bond between the third and fourth carbon atoms in a chain of seven carbon atoms.

Nonane has a total of 75 isomers, which includes straight chain isomers, branched chain isomers, and cyclic isomers.
Three isomers of C2HfClBr are possible.
C3H4O can have two isomers: propynal and cyclopropanone.
There are two isomers for dibromopropane: 1,2-dibromopropane and 2,2-dibromopropane.
There are a total of three structural isomers of C7H16 that have no secondary hydrogen atoms. These isomers are 2-methylhexane, 3-methylhexane, and 2,2-dimethylpentane.

C10H18. However, the compound is named incorrectly; it should be 5-ethyl-3-octyne.
This compound (dibromomethane) has only one form. It does not form isomers .
None, as it has 5 structural isomers in which none of are optically active.
