The product that results when citronellal is treated with excess H 2 in the presence of a Pd catalyst should be determined. Concept Introduction: Hydrogenation is the reaction of alkenes or alkynes with hydrogen gas. This is an addition reaction. H 2 is added across the C-C double bonds of alkene, triple bonds of alkynes. But this reaction occurs only in the presence of a metal catalyst like palladium. In a reduction of an organic molecule, either the number of C-O bonds decreases or number of C-H bonds increases. So when an aldehyde is reduced by H 2 in the presence of Pd catalyst, C=O double bond is reduced to C-O single bond and H 2 is added across this C=O double bond forming a primary alcohol.

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.

The velocity distribution function of gas moleculesa) is used to measure their velocity, since the small size of gas molecules means that it cannot be measured in any other wayb) is only used to describe the velocity of particles if their density is very high.c) describes the probability that a gas particle has a velocity in a given interval of velocities

Explain why in the representation of a one-dimensional velocity distribution function for a particular gas, the maximum occurs for vi = 0 m/s.

Explain why the representation of a one-dimensional velocity distribution function for a particular gas becomes flatter as the temperature increases.
