ETHYNE AN ETHENE GAS EXPERIMENTS

WHY WOULD YOU EXPECT THE FIRST TEST TUBE OF GAS COLLECTED TO BE LESS PURE THEN THE OTHER S

DISPLACED AIR

WHAT WOULD BE OBSERVED IF A FEW DROPS OF BROMINE WAS ADDED TO THE TEST TUBE OF ETHYNE GAS

BROWN TO COLOURLESS

WHAT WOULD BE OBSERVED IF A FEW DROPS OF KMnO4 WERE ADDED TO A TEST TUBE OF ETHYNE GAS

PURPLE TO COLOURLESS

WHAT DOES A SUCCESFUL BROMINE/KMnO4 TELL US ABOUT EHTYNE GAS

UNSATURATED BONDS PRESENT

HOW DO YOU TEST FOR UNSATURATION

ADD KMnO4 OR BROMINE WATER

DESCRIBE HOW YOU WOULD TEST IF ETHYNE GAS IS FLAMMABLE

INSERT LIGHTING TAPER INTO TEST TUBE

DESCRIBE THE FLAME OBSERVED WHEN ETHYNE COMBUSTS

BLACK SOOTY FLAME

HOW DOES THE FLAME USED IN WELDING DIFFER FROM THE FLAME OBSERVED DURING ETHYNES COMBUSTION TEST

WELDING FLAME IS BLUE

WHAT TYPE OF BOND IS PRESENT IN ENTHENE AND ETHYNE GAS

UNSATURARTED BONDS

WHAT GAS WHEN MIXED WITH TOLLENS REGANT AND WARMED GENTLY FORMS A SILVER MIRROR

ETHANAL

OTHER THAN ADDING TOLLENS REAGANT WHATS ANOTHER METHOD TO IDENTIFY THE PRESENCE OF ETHANAL

ADD FEHLINGS REAGENT , WARM GENTLY , BRICK RED PRECIPITATE FORMED

HOW DO YOU AVOID SUCKBACK DURING THE ETHENE GAS EXPERIMENT

REMOVE TUBING FROM WATER BEFORE REMOVING HEAT SOURCE

NAME THE TYPE OF REACTION THAT OCCURS WHEN BROMINE WATER IS ADDED TO ETHENE

AN ADDITION REACTION

IDENTIFY AN ORGANIC PRODUCT OF THE REACTION BETWEEN ETHENE AND BROMINE WATER

1,2-DIBROMOETHANE
