Aim The purpose of carrying out this experiment is to identify Alkanes and Alkenes by their reactions … Chemistry Lab Report - Reaction of Alcohol.

For example: Our team of exam survivors will get you started and keep you going. Read about our approach to external linking. The presence of the C=C double bond allows alkenes to react in ways that alkanes cannot. Small samples of the liquids are also ignited and the appearance of the flames compared. /Length 4867 Expt 7 Classification Tests for Hydrocarbons. This activity compares the reaction with bromine water of several liquid alkanes and alkenes.

Alkanes produces less colour intensity and less soot given off during combustion test compared to alkenea. >> Academia.edu is a platform for academics to share research papers. Laboratory 21: Properties of Alkanes, Alkenes, and Alkynes Introduction Hydrocarbons are organic compounds composed entirely of carbon and hydrogen atoms. 3.2 Alkanes; 3.3 Haloalkanes; 3.4 Alkenes; 3.5 Alcohols; 3.6 Organic analysis (AS): analytical techniques; A2 Chemistry. %PDF-1.5 The test for unsaturation is demonstrated. 1. … Try the free Mathway calculator and This allows us to tell alkenes apart from alkanes using a simple chemical test. Introduction In the study of organic chemistry, the organic compounds which are made up of carbon and hydrogen are called hydrocarbons. Alkenes can decolourise bromine water, but alkanes cannot. problem and check your answer with the step-by-step explanations. The bromine is decolourised because a colourless dibromo compound forms. Please submit your feedback or enquiries via our Feedback page. A2 Physical. Download Now. The reaction between bromine and alkenes is an example of a type of reaction called an, . For example: C, Home Economics: Food and Nutrition (CCEA). They are obtained primarily from natural sources such as coal, petroleum, and natural gas. Upload. Hypothesis Alkenes are much more reactive than alkanes. Alkanes and alkenes are both families of hydrocarbons. This has the effect of ‘saturating’ the molecule, and will turn an alkene into an alkane. 8�����������HÊ��PU��} E�0"'z�n['������,�Н_w���R�nO=�l�8�'������� t/� I̤�o��ۆBh�����C'D�sw"'H1�`�v!���J����������/��z0�Ir�vδ�]h�!U�j�� �o�!d��� fЀa���} �_"��Sd��';�#"6�+���Ű�LB�,`5������u��ė��NP��g��c���Sg\��A(���ʮ4ӶZH���Rw/a`�\��~~��*� �� p2��m���?f��bT�ž�!�����F�]o�ь��#��L�T��J /�V.
