Question

what do you mean by parental chain?

Answer 1

In IUPAC nomenclature, a parent structure, parent compound, parent name or simply parent is the denotation for a compound consisting of an unbranched chain of skeletal atoms (not necessarily carbon), or consisting of an unsubstituted monocyclic or polycyclic ring system. [1] Parent structures bearing one or more functional groups that are not specifically denoted by a suffix are called functional parents. [2] Names of parent structures are used in IUPAC nomenclature as basis for systematic names.

Answer 2

Parental is used to describe something that relates to parents in general, or to one or both of theparents of a particular child. Medical treatment was sometimes given to children without parental consent.
