Abstract

I. Introduction

Hydrocarbons are one of the

basic organic compounds there is.[] A

hydrocarbon, as its name implies,

consists of only covalent hydrogen-

carbon bonds. These organic

compounds are mainly classied as

aliphatic or aromatic. Aliphatic

hydrocarbons are classied according

to its carbon chain skeleton, acyclic

open-chained! or cyclic closed-

chained!. Also, according to the bonds

present, saturated hydrocarbons

"hich only have single covalent bonds

or unsaturated hydrocarbon "hichhave at least a double or triple

covalent bond in its structure.

Aromatic hydrocarbons are mainly

composed of ben#enes $ig. %.&.!,

those that contain alkyl side chains are

called arenes.[] %n the e'periment, si'

di(erent organic compounds "ere

used namely, he'ane, heptane,

cyclohe'ane, cyclohe'ene, ben#ene

and toluene. $or every classication of 

the given samples of hydrocarbons,there is a corresponding test that

"ould help identify it. The importance

of classifying hydrocarbons is that it

enables researchers to identify the

certain characteristic that "ould either

be benecial or harmful to"ards its

intended use.[]

 The intended learning outcomes

of this e'periment are to analy#e and

classify hydrocarbons, di(erentiate

hydrocarbons in terms of their intrinsicphysical properties and chemical

properties based on their structure

and behavior.[]

II. Methodolgy

$or this e'periment, the group used

the follo"ing organic compounds)

he'ane, heptane, cyclohe'ane,

cyclohe'ene, ben#ene and toluene to

di(erentiate each "ith the aid of 

several tests. $irst, the physical state,color and odor of the samples "ere

taken note of. The tests then

proceeded as follo"s)
