CONCEPTS IN ORGANIC CHEMISTRY • Inductive Effect : Inductive effect is defined as permanent displacement of shared electron pair in a carbon chain towards more electronegative atom or group. Types of Inductive effect : 1.Negative Inductive Effect : (—I effect‚ Electron withdrawing effect) when an electronegative atom or group (more electro negative than hydrogen)is attached to the terminal of the carbon chain in a compound‚ the electrons are displaced in the direction of the attached

At this time in our world we live in I do believe nuclear terrorism is a huge threat and the U.S. should be very concerned about it. It was noted by Jeffrey T. Richelson that “declassified documents have confirmed that the U.S. (and other) governments have anticipated the possibility of a terrorist nuclear incident at such high-profile events as the 2009 inauguration of President Barack Obama and the 2010 Vancouver Olympics” (Richelson 2012). United States government officials have been concerned

have sought to use it for the benefit of the people‚ and radiation therapy is only one example. Nuclear engineering is a wide field that covers important subjects of study from the disposal of nuclear fuel and waste to the maintenance of systems such as nuclear reactors‚ plants‚ and even weapons (Shiori‚ “Nuclear Engineering Education”). Although the amount of advances has been minimal over the years‚ nuclear engineering is still a stable field of study and necessary for a highly civilized country to

Ionic Reactions Introduction: Today we are going to observe the chemical changes when mixing two solutions. Some will change colors‚ produce gases proving if the solutions are soluble or insoluble. Materials and Methods: I first pulled out the small wells and place two drops of the Cobalt (II) Nitrate in seven of the wells. I then moved to the next row and placed two drops of Copper (II) Nitrate in the next row‚ into seven of the wells‚ and so on with the other three Nitrates. I then cut off

are depending more and more on nuclear energy to produce electricity. Although‚ nuclear energy can bring many benefits‚ such as nuclear fission‚ which releases no carbon dioxide‚ it also brings many risks to many countries that use nuclear energy. This was proved‚ in many disasters that nuclear energy caused years ago‚ like the Chernobyl Disaster in April 26‚ 1986‚ which was said that‚ “the radiation released was to be 200 times that of Hiroshima and Nagasaki nuclear bombs combined (Smashing Lists
