(a) Interpretation: The product with the detailed mechanism for the given reaction is to be drawn. Concept introduction: The aldehyde or ketone can also be halogenated like alkylation by deprotonation of α carbon followed by a nucleophilic substitution reaction with the halogen molecule. In the basic condition, multiple halogenation at α carbon of aldehyde or ketones can be possible. In the first halogenation, the substitution of halogen takes place at α carbon of ketone by the formation of enolate anion due to deprotonation. The α carbon of ketone becomes more acidic after the first halogenation and can form a second enolate anion. The second enolate is more stable compared to the first one and undergoes further halogenation. This is due to the electron withdrawing effect of electronegative halogen atom, which stabilizes the negative charge on α carbon.

Question

Choose the Lewis structure for the compound below: H2CCHOCH2CH(CH3)2 HH H :d H H H C. Η H H HH H H H H. H H H HH H H H H H- H H H C-H H H HHHH

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

Concept introduction:

The aldehyde or ketone can also be halogenated like alkylation by deprotonation of α carbon followed by a nucleophilic substitution reaction with the halogen molecule. In acidic condition, the reaction stops at a single halogenation step and no multiple halogenation occurs. The reaction proceeds via the formation of enol by protonation of carbonyl oxygen.
