Predict the product 'B' in the sequence of reaction `HC equiv CH overset (30% H_(2) SO_(4))underset(Hg SO_(4)) to A overset (NaOH) to B`

Options

A. `CH_(3)COONa`
B. `CH_(3)COOH`
C. `CH_(3)CHO`
D. `H_(3)-underset(OH)underset(|)CH-CH_(2)-CHO`

Answer

4

Explanation

`HC-=CHoverset(30%H_(2)SO_(4))underset(HgSO_(4))toH_(2)C=overset(O-H)overset(|)(CH)toCH_(3)-overset(O)overset(||)C-H(A)` aldol addition `darrNaOHCH_(3)-underset(OH)underset(|)CH-CH_(2)-CHO` (B)
