Answer 1

The correct answer is Cyclopropane.

Key Points

Cyclopropane consists of three carbon atoms arranged in a triangular ring, with each carbon bonded to two hydrogen atoms.
The bond angles in cyclopropane are approximately 60°, which is much smaller than the ideal tetrahedral angle of 109.5°.
The carbon-carbon bonds in cyclopropane are single bonds (σ-bonds), but the strain causes them to be weaker and more reactive than typical single bonds in larger rings or chains.

cyclopropane is more reactive compared to other hydrocarbons, and it readily undergoes reactions such as ring-opening and addition reactions.

Additional Information

Isobutane, also known as 2-methylpropane, is a branched-chain alkane with the formula C₄H₁₀.
Isobutane has a compact, branched structure where three carbon atoms form a chain, and the fourth carbon is attached as a branch.
Uses: Refrigerant, fuel for portable stoves, propellant in aerosols.
Properties: Colorless, odorless gas with a lower boiling point than n-butane.

Acetic acid has the formula CH₃COOH.
It consists of a carboxyl group (COOH) attached to a methyl group (CH₃).
Acetic acid is widely used as a vinegar ingredient for culinary purposes, as well as in the production of chemicals like acetic anhydride and acetate esters.
It's also used in the textile industry and as a solvent.

Ethane has the formula C₂H₆. It consists of a two-carbon chain with each carbon atom bonded to three hydrogen atoms.
Ethane is primarily used as a feedstock in the production of ethylene, which is a key raw material for manufacturing plastics and other chemicals.
It is also used as a fuel and in refrigeration.
