SSC CPO 2022 Tier-I Official Paper (Held On 11 Nov 2022 Shift 2) [Answer Key]

Saturated hydrocarbons are fairly unreactive and are inert in the presence of most reagents.
Most carbon compounds also release a large amount of heat and light on burning.
Carbon compounds cannot get oxidised on combustion.
Unsaturated hydrocarbons add hydrogen in the presence of catalysts such as palladium or nickel to give saturated hydrocarbons.

Answer 1

The correct answer is Carbon compounds cannot get oxidized on combustion.

Key Points

In a combustion reaction, carbon compounds are oxidized in the presence of oxygen. So option 3 is incorrect.
Though combustion is generally an oxidation reaction, not all oxidation reactions are combustion reactions.
Oxidation is also carried out by using oxidizing agents (Oxidants).

Important Points

Saturated hydrocarbons don't have a double or triadic bond to suffer an addition reaction.
They can generally suffer a negotiation response where one snippet is replaced with another group.
Impregnated hydrocarbons are fairly inert in the presence of utmost reagents.
However, in the presence of sunlight, chlorine is rapidly added to hydrocarbons.
Many carbon compounds release a very large amount of heat and light on burning.
This chemical process in which a substance burns rapidly in presence of oxygen to give heat and light is called combustion.
Unsaturated hydrocarbons add hydrogen in the presence of catalysts such as Nickel and Palladium.
Through this process, the unsaturated hydrocarbons get converted into saturated ones.
This process is known as an addition reaction.
