Draw the structure of the following :
(i) 3-Methylbutanal , (ii) p-Methoxybenzaldehyde , (iii) 4-Chloropentan-2-one
(iv) p,p-Dihydroxybenzophenone, (v) p-Nitropropiophenone , (vi) 4-Methylpent-3-en-2-one,

Explanation

(i) `underset("3-Methylbutanal")(overset(4)(C)H_(3)-overset(CH_(3))overset(|)(.^(3)C)H-overset(2)(C)H_(2)-overset(1)(C)HO)`
(ii) `underset("4-Chloropeentan-2-one")(overset(5)(C)H_(3)-overset(Cl)overset(|)(.^(4)C)H-overset(3)(C)H_(2)-overset(O)overset(||)(.^(2)C)-overset(1)(C)H_(3))`.
