The product formed in the aldol condensation of acetaldehyde is

Options

A. `CH_(3)CH_(2)CH(OH)CHO`
B. `CH_(3)CH(OH)CH_(2)CHO`
C. `CH_(3)CH(OH)COCH_(3)`
D. `CH_(3)CH_(2)CH_(2)CHO`

Answer

B

Explanation

Two molecules of acetaldehyde combine with each other in presence of dil. NaOH to fomr 3-hydroxybutanal.
`CH_(3)CHO+HCH_(2)CHO overset(OH^(-))to underset("3-hydroxybutanal(aldol)")overset(OH) overset(|) (CH_(3)-CHCH_(2)-CHO)`
