Abstract: In this experiment‚ the methyl nitrobenzoate was prepared from methyl benzoate‚ concentrated HNO3‚ and concentrated H2SO4 via an electrophilic aromatic substitution reaction. The HNO3 and H2SO4 were combined to form a nitrating solution‚ which was mixed with a mixture of methyl benzoate and H2SO4. Percent yield for the final product was calculated followed by recrystallization and melting point was measured. Introduction: Nitration of Methyl Benzoate is one of the examples of

Gluck uses strong diction to create vivid images in order to convey the hatred and helplessness that is the core of the character. Although the diction is relatively colloquial‚ there are some prominent words‚ which are utilized to exhibit the woman’s emotions. The first two lines of the poem are bursting with powerful lexis‚ "It is not the moon‚ I tell you. / It is these flowers..." (1-2). The woman hates men‚ and uses influential words to aid in her belief. The word moon suggests power. The subject
