Write the possible isomers for the formula `C_(5)H_(12)` with their names and structures.

Explanation

(i) `underset("n-pentane")(CH_(3)-CH_(2)-CH_(2)-CH_(2)-CH_(3))` (ii) `underset("Isopentane")(CH_(3)-underset(CH_(3))underset(|)(CH)-CH_(2)-CH_(3))`
(iii) `underset("Neopentane")(CH_(3)-underset(CH_(3))underset(|)overset(CH_(3))overset(|)C-CH_(3))`
(i), (ii) and (iii) are chain isomers
