Primary and secondary groups

broken bond between carbon and the delta negative leaving group. The stereochemistry is inverted at the alpha carbon as the C-I bond fully forms. Then the leaving group comes off of the molecule taking the electrons it shared with the alpha carbon. The reason that only 1-chlorobutane and 1-bromobutane formed a precipitate is because the carbon that bears the leaving group is primary. An SN2 reaction mechanism works the best (and fastest) with primary substrates due to less steric hindrance being…

199 different nationalities in Ireland. Some of the nationalities with the largest population are Polish, United Kingdom, Lithuanians, Latvians, Nigerians and Romanians (Kenny, 2012). The two main religious groups in Ireland are Roman Catholic and Protestant. Historically, these religious group clashed because of the difference in opinion on the status of Ireland (BBC News, 2016). The Protestants wanted Ireland to be a part of the United Kingdom, and the Catholics wanted Ireland to be…

that currently seems permanent, as there are not pharmacological therapies to reverse the primary mechanical injury. However, the secondary SCI may be reduced using the proper rehabilitation techniques. Pivotal components of the secondary injury pathway include ischemia and hypoxia, lack of blood supply and lack of oxygen, respectively, that may lead to programmed cell death, or apoptosis. Once the secondary pathway is onset, it triggers the activation of many inflammatory molecules that can be…

throughout life can usually be categorized into one of two groups: primary and secondary. Each category has its own benefits and can influence a person in completely different ways. One group that nearly every person on the planet has the opportunity to interact with is the institution of family. The most obvious form of a primary group, family serves as a emotional net to help guide one through life. My immediate…

individual has with their peers and group members. It does not necessarily have to be criminal behavior that is learned, any behavior can be picked up but the importance is stressed between learning behavior from continuous interactions with others. Therefore, deviance is learned from an individual associating with a group of deviants and picking up or learning the behavior from the group. An example of this is underage drinking. If an individual hangs out with a group of peers that go out and…

may also be some loss of biological activity. However, the primary structure will not be disrupted when a protein denature as a large amount of energy is needed to break down the relatively strong peptide bonds in the primary structure. Some of the factors resulting in the denaturation of proteins are heat and change in pH or potential of hydrogen. An increase in temperature will disrupt the weak forces of attraction between the R groups such as hydrogen bonds, Van der Waales forces and induced…

establish a clear distinction between primary and secondary qualities that are perceived in bodies. To prove this, Locke argues that primary qualities are solidity, extension, figure, rest, motion and inhere in a body. Then, he proposes that secondary qualities are color, tastes, sounds, and smells that are separable from a body and are rather powers to produce sensations in us by the use of their primary qualities. Therefore, primary qualities inhere in objects and secondary qualities are…

Hispanic children’s participation rates in early childhood education programs are significantly low compared to Caucasian students due to economic disadvantages. The low socioeconomic status of Hispanics has led to lower achievement levels in primary and secondary schools, which is an extension of the lack of early childhood education enrollment. The data does show that Hispanic parents value early childhood education programs and at least know of them. Researchers found evidence to reflect…

There are two fairly commonly used methods of dealing with occupational stress and they are tertiary level stress interventions which consists of Employee Assistance Programs (EAP) and secondary level stress intervention which consists of stress management programs. According to the U.S. Office of Personnel Management, Employee Assistance Programs are “voluntary, work-based programs that offer free and confidential assessments, short-term counseling, referrals, and follow-up services to…

Competitors such Audi, Mercedes-Benz, Bentley are some of the rising threats to BMW. As BMW uses both the type of data collection techniques – that is primary and secondary – the marketing strategies are effective and helps in establishing a strong customer base and brand image by bring out new innovated series. By using questionnaires as my primary research tool, we got the quantitative facts and figures such as preferences and priorities of people, their desires related to automobiles and…
