Write sturcutre of the following compound :
(i) p-Methyl benzaldehyde.

Explanation

(i) `CH_(3)-underset(CH_(3))underset(|)(C)=CH-overset(O)overset(|)(C)-CH_(3)`
(ii) `CH_(3)-overset(CH_(3))overset(|)underset(OH)underset(|)(C)-underset(OH)underset(|)overset(CH_(3))overset(|)(C)-CH_(3)`
(iii) `CH_(3)-overset(O)overset(||)(C)-underset(CH_(3))underset(|)overset(CH_(3))overset(|)(C)-CH_(3)`
(iv) `CH_(3)CH(OH)CH_(2)CHO`
(v) `CH_(2) = CH-COCH_(3)`
(vi) `CH_(3)-underset(CH_(3))underset(|)(C)=CH-overset(O)overset(||)(C)-CH=underset(CH_(3))underset(|)(C)-CH_(3)`
(vii) `underset(C_(6)H_(5))underset(|)(HC)=HC-CHO`
(viii) `C_(6)H_(5)-overset(O)overset(||)(C)-CH_(2)-CH_(3)`
(ix) `CH_(3)underset(CH_(3))underset(|)(C)HCH_(2)CHO`
(x)
(xi)
