Which of the following compounds will undergo aldol condensation, which the Cannizzaro reaction and which neither ? Write the structures of the expected products of aldol condensation and Cannizzaro reaction.
2-Methylpentanal

Explanation

2-Methylpentanal contain one or more `alpha`-hydrogen atoms and hence undergo aldol condensation. The reactions and the structures of the expected products are given below:
`underset("2-Methylpentanal ")(2CH_(3)CH_(2)CH_(2)-underset(CH_(3))underset(|)(CH)-CHO)overset(Dil. NaOH)tounderset("3-Hydroxy-2, 4-dimethy1-2-propylheptanal")(overset(7)(CH_(3))overset(6)(CH_(2))overset(5)(CH_(2))-underset(CH_(3))underset(|)overset(4)(CH)-underset(OH)underset(|)overset(3)(CH)overset(2)(-)underset(CHoverset(1)O)underset(|)overset(CH_(3))overset(|)C-CH_(2)CH_(2)CH_(3))`
