In-phase and out-phase stretching modes

Acetylene has two C=H groups. It will have two C-H stretching frequencies, the in-phase and out-phase stretching modes. The in-phase (symmetric) stretch occurs at 3374/cm and the out of phase stretch at 3333/cm. Explain why the in phase vibration is located at a higher frequence than the out of phase stretch in the case of a

Identify the Hydrocarbon

A hydrocarbon A (C6H10) burned a yellow, almost nonsmoky flame. On catalytic hydrogenation over platinum catalyst it absorbed 1 mold of hydrogen to form Compound B. it also decolorized a Br2-CH2Cl2 solution to yield a dibromo derivative, C. Ozonolysis of the hydrocarbon gave only one compound, D. Compound D gave a positive i

Presence of Aldehyde Group

An excellent way to identify the presence of an aldehyde group is by 1H NMR. The chemical shift of the aldehydic proton occurs in the 9-10-ppm region, where few other proton signals occur. Why is this chemical shift so far downfield?

Stability of Benzylic Carbocation

A benzylic carbocation is generated under the conditions of part A. Would the presence of a para CH3O- group on the benzene ring increase or decrease the stability of the benzylic carbocation? Explain.
