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

Nations watched and cheered on Terra’s distant shore As one man finally took a step no one ever took before In our hearts and in our minds his words will be enshrined “That’s one small step for a man‚ one giant leap for mankind.” (Roy Jerden‚ 2013) The final line of that poem was uttered in 1969‚ a time period when the United States and the Soviet Union did not fight with the blistering heat of gunfire‚ but with the cold progress of proxy wars and technological prowess. Neither of these superpowers

heated up the earth 1.4 degrees between now and 1880. Water is rising and warming causing more sea life deaths. Carbon dioxide emissions have gone up rapidly. We have a natural rising and lowering in earths temperature every 100‚000 years because of orbital forcing. We are causing this process to go faster. Solar radiation is making the Earths temperature rise. Those things are adding to global warming but some things slow down the process like trees taking CO2 out of the air‚ companies

Space tourism has been derided as a ‘playground for the rich’. But as demand grows‚ the cost of space travel might come down and even the middle class may soon be able to sign up for tours to outer space. Many companies are trying to make sub-orbital flights affordable to the public. In India‚ people like Jay Patel‚ a diamond trader‚ and Santhosh George Kulangara have signed up as space tourists. They will be among the first space tourists from India. Santhosh George‚ who hails from Kerala

over 1‚350 comets during the mission‚ but what they found was considered officially periodic. Many comets that SOHO has discovered have been identified as periodic‚ meaning that they follow their orbits around the sun more than twice and also have orbital periods that consists of less than 200 years. Astronomers have seen thousands of comets but have around 190 of them that fall under being periodic. The purpose of the SOHO mission was keep track of the sun and its orbit. So in essence‚ we were basically

INTRODUCTION Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years. It may be a change in average weather conditions or the distribution of events around that average (e.g.‚ more or fewer extreme weather events). Climate change may be limited to a specific region or may occur across the whole Earth. The most general definition of climate change is a change in the statistical properties of
