I. `CH_(2)=CH-CH_(3)+H_(2)O overset(H^(+))(rarr)`
II. `CH_(3)-CHO overset(CH_(3)MgI//H_(2)O)(rarr)`
III. `CH_(2)O underset(H_(2)O)overset(C_(2)H_(5)MgI)(rarr)`
IV. `CH_(2)=CH-CH_(3) overset("Neutral "KMnO_(4))(rarr)`

Options

A. I and II
B. II and III
C. III and I
D. II and IV

Answer

A

Explanation

I. `CH_(3)CH=CH_(2)+H_(2)Ooverset(H^(+))rarr CH_(3)overset(OH)overset("| ")"CH"CH_(3)`
II. `CH_(3)CHO overset((i) C_(2)H_(5)MgI)underset((ii)H_(2)O)rarr CH_(3)overset(OH)overset("| ")"CH"C_(2)H_(5)`
III. `CH_(2)O overset((i)C_(2)H_(5)MgI)underset((ii)H_(2)O)rarr C_(2)H_(5)CH_(2)OH`
IV. `CH_(2)CH=CH_(2)overset(KMnO_(4))underset("neutral")rarr CH_(3)underset(OH)underset("| ")"CH" underset(OH)underset("| ")(CH_(2))`
