The structures for the compounds A and B that are produced in the photochemical chlorination of the given alkane are to be deduced and the factors that influencing their distribution are to be discussed. Concept introduction: If the hydrogens in alkanes are not equivalent the chlorination produces a mixture of constitutionally isomeric products. In propagation step, a substituent may abstract a hydrogen atom either from a primary or secondary or tertiary positions in the propagation step. Among alkanes, tertiary hydrogens are replaced faster than secondary, and secondary faster than primary. The ratio of the monochlorination products depends on the type of hydrogen that is abstracted by the chlorine atom and the free radical that is formed. In S N 1 hydrolysis reaction, the rate of hydrolysis depends on the position of the halogen group present. The order is tertiary halides > secondary halides > primary halides .

The structures for the compounds A and B that are produced in the photochemical chlorination of the given alkane are to be deduced and the factors that influencing their distribution are to be discussed.

Concept introduction:

If the hydrogens in alkanes are not equivalent the chlorination produces a mixture of constitutionally isomeric products. In propagation step, a substituent may abstract a hydrogen atom either from a primary or secondary or tertiary positions in the propagation step.

Among alkanes, tertiary hydrogens are replaced faster than secondary, and secondary faster than primary.

The ratio of the monochlorination products depends on the type of hydrogen that is abstracted by the chlorine atom and the free radical that is formed.

In SN1 hydrolysis reaction, the rate of hydrolysis depends on the position of the halogen group present. The order is tertiary halides>secondary halides>primary halides.

Under milder temperatures than what is needed for dehydration, strong acids catalyze the self-condensation of 1-propyl alcohol to give di-n-propyl ether. The mechanism differs from that of today's reaction in that the protonated alcohol undergoes an Sn2 rather than an Sn1 reaction. Write the mechanism for the acid catalyzed condensation of ethyl alcohol to give diethyl ether. Make sure the mechanism includes protonation, Sn2, and deprotonation.

5. Acetone and 2-propanol are chemically interconvertible. Reduction (by the addition of the equivalent of H2) of acetone yields 2-propanol. Conversely, oxidation (by the removal of the equivalent of H2) of 2-propanol yields acetone. Is the evaporation data for these substances the same or different? If different, can you account for why this may be the case from a comparison of the Lewis structures of each substance and the IMFs present in each substance? Explain.

the organic compound 2-heptanone, belonging to the ketone family, is responsible for the strong penetrating odor in Roquefort cheeses. Starting from acetylene as the starting reagent, propose a synthesis line with the reaction mechanisms involved for the synthetic obtaining of 2-heptanone and use it as a food additive in analogous cheeses.
