(a) A compound ‘X’ is C2H4. Draw its electron dot structure. Will it dissolve in water or not? Will it conduct electricity in aqueous solution? Will it have high melting or low melting point?
(b) A compound ‘X’ has molecular formula C4H10. It undergoes substitution reaction readily than addition reaction. It burns with blue flame. It is present in LPG. Identify ‘X’ and give the balanced equation for its combustion and substitution reaction with Cl2 in presence of sunlight.
(c) Why are vegetable oils healthy as compared to vegetable ghee? How are vegetable oils converted into vegetable ghee? Name the process.
Answers
Answer:
a no it not dissolve in water
no it doesn't conduct electricity
Explanation:
because it is covalent compound
Ethene, Butane, Hydrogenation
Explanation:
(a) Ethene
Ethene is a non-polar molecule and does not dissolve in water. So it does not not conduct electricity in aqueous solutions. Ethene has low melting point. Please refer the attached picture for the electronic dot structure.
(b) Butane.
Combustion: 2C4H10 + 13O2→ 8CO2 + 10H2O
Substitution:
C4H10 + Cl2 ----sunlight----> C4H9Cl + HCl
C4H9Cl + Cl2 ----sunlight----> C4H8Cl2 + HCl
The substitution reaction continues until all H is replaced by Cl.
(c) Vegetable ghee contains saturated carbon chains which are harmful to health. Vegetable oil contains unsaturated carbon chains and hence recommended for use. Vegetable oils are converted into vegetable ghee by hydrogenation in the presence of a catalyst like nickel.
