- Build a model of methylcyclohexane, and use the model to complete the following Newmanprojections of methylcyclohexane in the chair conformation: a. When the methyl group is in an axial or equatorial (circle one) position, the molecule is inits lowest potential energy conformation. b. Label one Newman projection above anti and the other gauche to describe the relationshipbetween the methyl group and C3 of the ring. c. In general, which is a lower PE conformation, anti or gauche? d. Explain how your answer to b and c provide an explanation for why it is more favorable fora large group to be in an equatorial than an axial position.I am slightly confused on the naming of ethers. How come for chloromethoxymethane, it is not methoxychloride? Isn't chloride more complex than the alkyl group, so it should be placed at the root? Or is it not placed at the root because chloride is not an alkyl group at all?Why does Hammett Equation only apply to meta and para substituted rings and not others? Explain
