When CH_2 = CH - COOH is reduced with LiAlH_4, the compound obtained will be

JEE Main 2003 Chemistry question

When is reduced with , the compound obtained will be

(1)CH_2 = CH - CH_2OHCorrect
(2)CH_3 - CH_2 - CH_2OH
(3)
(4)

Answer: (1)

Solution

(hydride donor) reduces the polar –COOH group to –CH₂OH but does not normally reduce an isolated (non-conjugated to the reaction centre after reduction) C=C double bond. So
