Ethyne ..Preparation of Ethyne (Acetylene)
Ethyne (acetylene) is the simplest alkyne and can be obtained by the following method..
Structure of ethyne (acetylene)
Ethyne (acetylene) can be described by the molecular formula C 2 H 2 . As each carbon atom in this molecule has two points of attachments, each carbon atoms in ethyne (acetylene) is sp hybridized. sp hybridization of carbon orbitals The two 'sp' hybrid orbitals are oriented..

Ethyne undergoes addition reactions to give saturated compound..
Alkynes
These hydrocarbons contain at least one carbon-carbon triple bond. For example, ethyne, propyn..
Physical Properties of Alkynes
The first three members (ethyne, propyne and butyne) are colourless and odorless gases. Due to the presence of phosphine as an impurity ethyne (acetylene) has garlic smell. The next eight members are liquids, and higher members are solids under normal conditions of tempera..
Oxidation
Oxidation of alkynes gives mono or dicarboxylic acids. For example, Alkaline KMnO4 oxidises ethyne to oxalic acid. oxalic acid(ethanedioic acid) With chromic acid, ethyne gives acetic acid. ethyneethanoic acid(acetylene)(acetic acid) Homologues of ethyne..

This is my favorite tutoring ever. i might say that to others to, but this tutoring has thought me the most from any tutorings!! -Ashlyn
This explained everything to me clearly and helped me so much and I think it has made a difference in my understanding. Its gone from small to big understanding ,I think it is a magnificent tutoring - Elizabeth
I need tutoring from tutorvista till th end of my schooling. Tutors are not only experts they are brilliant enough to make a student like me understand the concepts of differentiation and functions.
The tutor remembered me from last week and noted my improvement. This is simply amazing :)
