![]() In this test, the orange-red colour of bromine solution disappears when it is added to the unsaturated hydrocarbon to form colourless addition products. There are two tests for detecting unsaturation in organic compound: These are the hydrocarbons which contain multiple (double or triple) carbon-carbon bonds. Unsaturated Hydrocarbons (Alkenes and Alkynes) Since carbon atoms can form long chains-straight as well as branched and rings, they are divided into two types: alkanes or aliphatic hydrocarbons and cycloalkanes. Because of the low reactivity, they are also called paraffins. These are i saturated hydrocarbons because the four valencies of all carbon atoms are satisfied with single bonds. These hydrocarbons contain single bonds only between C-C and between C-H. The hydrocarbons are classified into saturated and unsaturated hydrocarbons. The other organic compounds are derived from hydrocarbons by replacement of one or more hydrogen atoms by other atoms or group of atoms (functional group) such as -OH, -CHO, -COOH, -Cl, etc. Some of the common functional groups present in organic compounds are:Ĭompounds containing only carbon and hydrogen are called hydrocarbons. Compounds having different functional groups have different properties and belong to different families of compounds. Different compounds having same functional group have similar properties and are classified as family of compounds. The properties of a compound are largely determined by the functional group. Molecules of organic compounds except that of hydrocarbons can be divided into two parts, a reactive part which is referred to as functional group and a skeleton of carbon atoms called alkyl group.

![]() In the past few days, pro-government forces have signaled that they are escalating efforts to press the tactics to their conclusion in Aleppo, step by step. The tactics have succeeded in much smaller areas: in encircled suburbs of the capital, Damascus, and in rebel enclaves in the central city of Homs - first in the historic Old City and, most recently, last week, in the outlying neighborhood of Waer. special envoy for Syria, Staffan de Mistura, warned on Sunday, speaking at an emergency Security Council session on Syria, in which outright confrontation replaced any effort to find diplomatic common ground.Įast Aleppo would be by far the biggest and most fortified area that government forces had sought to retake with scorched-earth tactics of siege and bombardment - called "starve-or-submit," after slogans scrawled outside besieged areas by pro-government militiamen. But it could pale in comparison with a military assault to retake all of Aleppo, once Syria's largest city and still home to about 2 million people, roughly 250,000 of them in rebel-held territory.Ī takeover battle could mean "a slow, grinding, street-by-street fight, over the course of months, if not years," the U.N. The killing and destruction in Syria, of course, has stupefied much of the world during the past five years. It is a strategy that both the Syrian government and its Russian allies have long embraced to subdue Syrian rebels, largely by crushing the civilian populations that support them.īut in the past few days, as hopes for a revived cease-fire have disintegrated at the United Nations, the Syrians and Russians seem to be mobilizing to apply this kill-all-who-resist strategy to the most ambitious target yet: the rebel-held sections of the divided metropolis of Aleppo. Repeat until a deserted cityscape is yours. Open an escape route, or offer a deal to those who leave or surrender. (Abdalrhman Ismail / Reuters)īEIRUT - Make life intolerable and death likely.

Also, the optical and electrical properties of the device such as absorption coefficient, indirect and direct bandgap transition, capacitance–voltage and conductance–voltage characteristics have been obtained and analysed with the help of Tauc and Bode plots. The device has been successfully compared with the previous works to showcase its performance enhancement. The final optimized solar cell has reached a Fill factor (FF) of 85.44%, a short-circuit current density ( J sc) of 31.12 mA/cm 2, a power conversion efficiency (PCE) of 32.36%, and an open-circuit voltage ( V oc) of 1.22 V. ![]() The optimal thickness of the perovskite layer has been found to be 400 nm that leads to a performance improvement of ~ 8%. The designed solar cell has been optimized by varying parameters such as active layer thickness, absorber defect density and work function of the bottom electrode. The design and performance of inorganic tin-based perovskite known as cesium tin iodide (CsSnI 3), which serves to be an alternative for conventional toxic lead-based solar cells have been reported. ![]() The game was localized to 50 languages and held the #1 spot in the TOP Overall in more than 15 countries.
