Question

An unsaturated hydrocarbon reacts with one mole of hydrogen to form a saturated compound Predict its formula.
CH3H4
C6H12
C4H10
C7H16

Answer 1

Answer:

Its C6H12

Explanation:

Last two are already saturated according to formula CnH2n+2 and 1st one is alkyne and it will become alkene after reaction Both are unsaturated For the 3rd one as it is alkene it will become alkyne Unsaturated to saturated.

Answer 2

An unsaturated hydrocarbon reacts with one mole of hydrogen to form a saturated compound, the formula must be C₆H₁₂.

• A saturated hydrocarbon has only sigma bonds present in its structure.

• Alkanes (with the general formula CₙH₂ₙ₊₂) are saturated compounds.
• Unsaturated compounds have one or more π bonds.
• Alkenes (with the general formula CₙH₂ₙ) and alkynes (with the general formula CₙH₂ₙ₋₂) are unsaturated compounds.
• Unsaturated compounds can be converted into saturated compounds using a hydrogenation reaction.
• 1 mole of hydrogen can convert an unsaturated compound with a single pi bond into a saturated compound.
• Out of the given options, only C₆H₁₂ have a single pi bond (alkene).
