1 / 5
Which molecule contains a carbon-carbon single bond?
Reasoning: ● Ethane (C₂H₆) has a single C-C bond.● Ethene and ethyne contain double and triple bonds respectively.Methanol has no C-C bond.
2 / 5
Which product is obtained when chloromethane (or methyl chloride) is reduced?
Reasoning: Reduction removes chlorine and replaces it with hydrogen:CH₃Cl → CH₄ (methane)
3 / 5
By hydrogenation we mean, the addition of:
Reasoning: Hydrogenation is the addition of H₂ to unsaturated compounds (usually in presence of catalyst).
4 / 5
Combustion of methane produces:
Reasoning: Methane burns in oxygen to form:● Carbon dioxide (CO₂) ● Water (H₂O) ● Heat energy
5 / 5
Reduction of chloromethane gives:
Reasoning: Reduction removes the chlorine atom from chloromethane and replaces it with hydrogen, producing methane (CH₄). Therefore, methane is the reduction product.CH₃Cl+2[H] → CH₄+HCl
