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.

2- Chromosomal mutations are changes in the structure or the numbers of chromosomes (a gain or loss). Gene mutations involve changes in the nucleotide sequence of the DNA molecule. 3-A gene mutation is a permanent change in the DNA sequence that makes up a gene. 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.. ex downs syndrom. 3 people found this useful.
