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.

Examples of spontaneous mutations include point mutations and frameshift mutations. Point mutations are the result of incorrect base pairings during cell division. If the amino acid code (triplet) is not altered by the change in bases, the point mutation is said to be synonymous. The resulting protein is not altered.
