Draw the structrue and name the product formed if the following alcohols are oxidized. Assume that an excess of oxidising agent is used.
(i) `CH_(3)CH_(2)CH_(2)CH_(2)OH`
(ii) 2-butenol
(iii) 2-methyl-1-propanol

Explanation

(i) `CH_(3)CH_(2)CH_(2)CH_(2)OH overset(K_(2)Cr_(2)O_(7)//H^(+))rarr underset("Butanoic acid")(CH_(3)CH_(2)CH_(2)COOH`
(ii) `CH_(2)-CH=Ch-overset(OH)overset(|)CH_(2)overset("PCC")underset("But-2en-lal")rarrCH_(3)-CH=CH-CHO`
(iii) `CH_(3)-underset(CH_(3))underset(|)(CH)-CH_(2)OHoverset(K_(2)Cr_(2)O_(7)//H^(+))rarrunderset(2-"Methyl propanoic acid")(CH_(3)-underset(CH_(3))underset(|)(CH)-COOH)`
