Question

An unsaturated hydrocarbon with three atoms of carbon and six atoms of hydrogen is:

• A. propyne
• B. propane
• C. propene
• D. propanol

Hint:

Remember the suffixes: -ane (single bond), -ene (double bond), and -yne (triple bond). Propene belongs to the alkene family.

Answer 1

The Correct Option is C

Step 1: Analyzing the Molecular Formula: 
The given information states the compound has 3 Carbon atoms and 6 Hydrogen atoms. The molecular formula is C_3H_6.
 
Step 2: Matching with General Formulas: 
Alkanes: C_nH_2n+2 (For n=3, H=8) Propane Alkenes: C_nH_2n (For n=3, H=6) Propene Alkynes: C_nH_2n-2 (For n=3, H=4) Propyne 

Step 3: Verifying Unsaturation: 
Unsaturated hydrocarbons contain double or triple bonds. Propene (C_3H_6) contains one carbon-carbon double bond, making it unsaturated. 

Step 4: Final Answer: 
The compound is propene.
