Ethanol is commonly known as alcohol and is the active ingredient in alcoholic drinks, making it a liquid at room temperature.

Coal and petroleum contain nitrogen and sulphur, and their combustion produces oxides of sulphur and nitrogen, contributing significantly to environmental pollution.

Gas/kerosene stoves are designed with air inlets to ensure an oxygen-rich mixture, resulting in a clean blue flame. If cooking vessels’ bottoms turn black, it signals blocked air holes, leading to inefficient combustion and wasted fuel.

Saturated hydrocarbons typically yield a clean flame, but if the air supply is restricted, incomplete combustion can occur, leading to a sooty flame due to the formation of carbon particles.

When a functional group with a suffix starting with a vowel (a, e, i, o, u) is present, the carbon chain’s name is modified by removing the final ‘e’ and adding the appropriate suffix. For example, a three-carbon chain with ...
