Write the structure formulae and IUPAC names for all the isomeric aldehydes and ketones of molecular formula, `C_5H_(10)O`.

Explanation

With the formula `C_(5)H_(10)O`, four aldehydes and three ketones are possible. Possible aldehydes are: (i) `underset("Pentanal")(CH_(3)-CH_(2)-CH_(2)-CH_(2)-CHO)` (ii) `underset("2-Methylbutanal")(CH_(3)-CH_(2)-CH(CH_(3))CHO)`
(iii)`underset("3-Methylbutanal")((CH_(3))_(2) CHCH_(2)CHO)` (iv) `underset("2,2-Dimethylpropanal")((CH_(3))_(3) C CHO)`
Possible ketones are:
(i) `underset("Pentanone-2")(CH_(3)-CH_(2)-CH_(2)-CO-CH_(3))` (ii) `underset("Pentanone-3")(CH_(3)-CH_(2)-CO-CH_(2)-CH_(3))` (iii) `underset("3-Methylbutanone")((CH_(3))_(3)CHCOCH_(3))`
