A mechanism for the formation of paraldehyde when three equivalents of acetaldehyde react in the presence of an acid catalyst is to be proposed. Concept introduction: The acid catalyst protonates an aldehyde molecule. The nucleophilic attack of the second molecule of acetaldehyde first on the protonated acetaldehyde followed by the attack of third molecule of acetaldehyde will produce an oxonium ion that has a free hydroxyl group. The internal nucleophilic attack of the hydroxyl group followed by the loss of a proton will yield paraldehyde. To propose: A mechanism for the formation of paraldehyde when three equivalents of acetaldehyde react in the presence of an acid catalyst.

Question

Indicate the correct option.a) Graphite conducts electricity, being an isotropic materialb) Graphite is not a conductor of electricityc) Both are false

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.
