Question 10

Alkene Reactions

Answer 10

Combustion same as alkane

Incomplete Combustion same as alkane.

Addtion reaction with Halogens.

Hydrogen Halide Reaction where product has to be written is displayed format with hygron going to first hydrogen-carbon compound.

Reacts with water to produce Alcohol.

Question 11

Fermentation

Answer 11

Yeast uses glucose to respire anaerobically producing ethanol and carbon dioxide.

Conditions:
pH 5-6
25 Degree Celsius
1 atm / 100kPa
Yeast

It uses renewable resources, batch process , very slow, ethanol produced needs to purified and low temperature required.

Question 12

Hydration Of Ethene

Answer 12

Ethene is reacted with water to produce Ethanol.

Conditions:
300 Degree Celsius
60-70 atm
Catalyst Concentrated Phosphoric Acid.

Uses non-renewable resources, continuous process, fast, producs pure ethanol, high temperature and pressure required.

Question 13

Alcohol Reactions

Answer 13

Combustion and incompelte combustion same as alkanes.

Dehydration using aluminium oxide as dehydrating agent to produce alkene and water.

Oxidation using oxidising agents such as Chromium Trioxide to produce carboxylic acid plus water. Heat under Reflux. Orange to green color.

Question 14

Carboxylic Acid Reactions

Answer 14

Dissociates in water to give Hydrogen Ions and
Respective -noates.

Reacts with Metal to formula metal-noates and hydrogen. Observations : Metal disappears , white solid forms and bubbles of hydrogen gas.

Reacts with metal carbonates to form metal-noates plus carbon dioxide plus water.
