by : Directorate of Education‚ Delhi SOME IMPORTANT REASONING BASED QUESTIONS OF ORGANIC CHEMISTRY 1. Chlorobenzene is less reactive than chloromethane. Ans. In chlorobenzene‚ each carbon atom of benzenering is sp2 hyridised and is electron withdrawing. Chlorine atom donates a lone pair of electron and acquire positive charge. The negative charge is delocalised on ortho and para position by resonance. C-Cl bond acquires partial double bond character and is 169 pm as compared to 17.0 pm in chloromethane

The purpose of this lab was to see which solutions are soluble and which are not. We were able to see this by mixing certain solutions together and observing changes that occurred. The procedure for this experiment included a few different steps. The first steps were to add the nitrate solutions into the lettered parts of the 96-well plate. Once you were done with that‚ you were supposed to add the sodium solutions to the numbered parts of the 96-well plate‚ so that the solutions were added together

Why is organic chemistry important? Organic compounds are used for many different things. Daily life in today’s world would be very hard to live in without organic compounds; in fact life would not be possible without organic compounds. For example‚ most of your body is made up of organic compounds. The food you eat is made up of organic compounds. Even the flavourings and colourings on processed food are organic. The clothes you wear are‚ yes you guessed it‚ organic as well. What’s more is that

Exercise 1 Polymers – An introduction to Organic Chemistry Group 3 Jude Marchoni C. Tampus Meryl Marie Susan Chua Pearl Pontillas Paolo Pepito Gaia Casas I. Abstract: (Paolo) In this experiment we will be testing what would happen to the polymer when we add borax to it. A polymer is a compound made up of large molecules often in a solid state. Polymers are chemically formed by 100 to 10‚000 small molecules called "monomers". Monomers occur in molecular units or patterns

1.1 CHEMISTRY 2213a ORGANIC CHEMISTRY FOR THE LIFE SCIENCES - organic chemistry is the study of life at the molecular level; to many it is the key to understanding life “The language of chemistry- an international language‚ a language without dialects‚ a language for all of time‚ and a language that explains where we came from‚ what we are‚ and where the physical world will allow us to go” (Nobelist Arthur Kornberg‚ a biochemist‚ 2000) - but its study has been challenging for students for
