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 alkene is converted in to a dibromo derivative by treating with Br₂ in the presence of CH₂Cl₂. The dibromo derivative is then treated with two equivalents of KOH when dehydrohalogenation takes place yield a terminal alkyne. The terminal alkyne is then converted in to its sodium salt. The sodium alkynide when treated with CH₃Br yields the next higher alkyne which when reduced by Li in liq.NH₃ produces the trans alkene.

To state:

Consider the following Figure 2 and two atoms that are initially an infinite distance apart, x =00, at which point the potential energy of the system is U = 0. If they are brought together to x = x, the potential energy is related to the total force P by dU dx = P Given this, qualitatively sketch the variation of U with x. What happens at x=x? What is the significance of x = x, in terms of the potential energy? 0 P, Force 19 Attraction Total Repulsion x, Distance Figure 2. Variation with distance of the attractive, repulsive, and total forces between atoms. The slope dP/dx at the equilibrium spacing xe is proportional to the elastic modulus E; the stress σb, corresponding to the peak in total force, is the theoretical cohesive strength.
