How many structural isomers can you draw for pentane?

How many isomers can be drawn for pentane with molecular formula C_5 H_12 ? What are they? Draw their structures and mention their common names.

How many structural isomers are possible in structure c_(7)H_(9)N Containing benzene ring:

Molecules having same molecular formula. But differing in structure (or) spatial orientation of atom is known isomers and phenomenon known as isomerism. Molecules which differ in structural formula are known as structural isomers and phenomenon is known as structural isomerism structural isomerism can be broadly classified as (i) Chain isomerism (ii) Positional isomerism (iii) Functional isomerism (iv) Metamerism (v) Tautomerism Molecules having same molecular formula but differing in spatial orientation are known as stereo isomers and the phenomenon known as stereo isomerism. Stero isomerism can be classified as (i) Geometrical isomerism (ii) Optical isomerism How many structural isomers possible for the given compound C_(4)H_(10)O
