(a) Whrite the structural formulae and give the IUPAC names for all the aldehydes and ketones of molecular formula, `C_(5)H_(10)O.`
(b) Write the function isomers of `C_(5)H_(10)O`, that can give Cannizzarpo's reaction
(c) A keto ester, `C_(6)H_(10)O_(3)` that forms oxime and by iodoform test ( with`I_(2)` and NaOH) forms `CH_(2)(COONa)_(2)` and structure

Explanation

Aldehydes : `(i) CH_(3)CH_(2)underset("Pentanl")(CH_(2))CH_(2)CHO " " (ii) CH_(3)underset(3-"Methylbutanal ")overset(CH_(3))overset(|)(CH)-CH_(2)CHO " " (iii) CH_(3)underset(2-"Methylbutanal")overset(CH_(3))overset(|)(CH)-CHO" " (iv)underset(2,2-"Dimethylpropanal")((CH_(3)))_(3)C-CHO`
Ketones : (i) `CH_(3)underset("Pentan"-2-"one")(CH_(2)CH_(2))COCH_(3)" " (ii)CH_(3)underset("Pentan"-3-"one")(CH_(2)COCH) " " (iii) CH_(3)-underset(3-"Methylbutan"-2-"one")overset(CH_(3))overset(|)(CH)-CO-CH_(3)`
