Carbon & its Compounds - 1 - UPSC MCQ

Butanone:

It contains a ketonic group. Ketones have suffix - one. Butane + one = Butanone

'Eth' tells that there are 2 Carbon atoms and 'yne' tells that there is a triple bond.

C₂H₄O₂ must be CH₃COOH since it turns blue litmus red and gives brisk effervescence with NaHCO₃ due to the evolution of CO₂.
CH₃COOH + NaHCO₃ → CH₃COONa + H₂O + CO₂

Chlorine reacts rapidly with saturated hydrocarbons in the presence of sunlight.
One such reaction is,
CH₄ + Cl₂→ CH₃Cl + HCl (in the presence of sunlight). This reaction is also called chlorination reaction.

The structure of the ethane molecule can be represented as:

There are six C-H bonds and one C-C bond . So, Total 6 convalent bond between C-H

 Three pairs of electrons are shared.

Methanol is alcohol having general formula C_nH_2n+1O. C₂H₆O, C₄H₁₀O, and C₇H₁₆O belong to the same series except C₅H₁₀O. Thus, C₅H₁₀O does not have the same chemical properties as methanol.

Oils on treating with hydrogen in the presence of palladium or nickel catalyst form fats. This is an example of addition reaction because hydrogen is added to oil from reducing agents palladium or nickel.

Buckminsterfullerene is an allotropic form of carbon. It resembles the geodesic dome designed by Buckminster.

Alkaline potassium permanganate acts as an oxidizing agent as it add oxygen to ethanol to form ethanoic acid.
