ions Reagent/ Condition; Reaction | Explanation | Oxygen supply; Combustion | Limited supply of oxygen: CO formed.Even less Oxygen: C is deposited as soot. Excess Oxygen: Complete combustion (giving CO2 and H2O) | Al2 O3 and vaporisation of alkane at 500°C; Cracking of Alkanes | Al2 O3 is used as a catalyst. Heat provides energy for breakage of C-C bonds. | UV light; Initiation step of FRS of alkanes by halogens * Not required for electrophilic addition reaction btw Halogens and alkenes

CHEM 1211 L Principles of Chemistry Lab 16 February 2004 Lab Report 1 Introduction The purpose of this project is to identify an unknown organic acid (X) by conducting various experiments to determine the acid’s unique properties. By determining selected constant properties of the unknown and then comparing these properties to the constant properties of known substances‚ it is possible to identify an unknown substance. The properties used to identify the unknown must be intensive‚ or independent
