Carboxylic acid derivatives react tend to react via nucleophilic acyl substitution where the group on the acyl unit, R-C=O undergoes substitution: Study Tip: Note that unlike aldehydes and ketones, this reactivity of carboxylic acids retains the carbonyl group, C=O. .The observed reactivity order is shown below:his reactivity order is important. You should be able to understand, rationalise and use it. It is useful to view the carboxylic acid derivatives as an acyl group, R-C=O, with a different substituent attached.
Influence of Prominent Abolitionists. Declaration of the Anti-Slavery Convention, 1833. The abolitionist movement took shape in 1833, when William Lloyd Garrison, Arthur and Lewis Tappan, and others formed the American Anti-Slavery Society in Philadelphia. The group issued this manifesto announcing the reasons for formation of the society and enumerating its goals.
By Robert McNamara. The abolitionist John Brown remains one of the most controversial figures of the 19th century. During a few years of fame before his fateful raid on the federal arsenal at Harpers Ferry, Americans either regarded him as a noble hero or a dangerous fanatic.

And the controversy over his actions and his fate helped stoke the tensions that pushed the United States to the brink of Civil War. Early Life. John Brown was born on May 9, 1800 in Torrington, Connecticut.
