The term may refer to any of three structural isomers, or to a mixture of them: in the IUPAC nomenclature, however, pentane means exclusively the n-pentane isomer; the other two being called isopentane (methylbutane) and neopentane (dimethylpropane). Cyclopentane is not an isomer of pentane.uch reactions are unselective; with n-pentane, the result is a mixture of the 1-, 2-, and 3-chloropentanes, as well as more highly chlorinated derivatives.
The four types of chromosomal mutation are deletion, duplication, inversion and trasnlocation. Deletion is the loss of all or part of a chromosome.Duplication is where a segm â¦ ent of a chromosome is copied. Inversion is where a section of a chromosome is reversed.he four types of chromosomal mutation are deletion, duplication, inversion and trasnlocation.

The two types of single gene mutations are point mutation, where a single point in the DNA sequence is affected, and FRAMESHIFT MUTATION, where a single gene or nitrogen base â¦ is deleted or added from the mRNA (messenger RNA) sequence causing a shift in the reading frame of the genetic message. gene mutation can be acquired throughout life or it is genetic ex sickle cell anemia chromsome mutations have more pronounced effects and are due to a change in the number â¦ of chromosomes or a change in the structural effect that are inherited..
