Answer:
Chemical formula of Heptane = C₇H₁₆
Step-by-step explanation:
Chemical formula of heptane
The chemical formula of heptane is C₇H₁₆
Chemical Structure of Heptane
Heptane is a member of the alkane series. It is an aliphatic hydrocarbon, it is a saturated hydrocarbon, i.e the carbon to carbon bond is a single bond. Heptane has nine isomers, and they are Heptane, 2-Methylhexane, 3-Methylhexane, 2,2-Dimethylpentane, 2,3-Dimethylpentane, 2,4Dimethylpentane, 3,3-Dimethylpentane, 3-Ethylpentane, 2,2,3-Trimethylbutane. Heptane has seven straight carbon to carbon chain. Heptane is a liquid at room temperature.
Properties of Heptane
⇒ It is a volatile substance
⇒ It is a colorless liquid
⇒ It is less dense than water
⇒It is insoluble in water
⇒ It has melting point is -91oC
⇒ it has boiling point is 98oC
⇒ It has a molar mass of 100 grams/mole.
⇒ It undergoes hydrocarbon combustion I.e combining with oxygen to from carbon(iv) oxide as shown in the reaction
C₇H₁₆(l)+ 11O₂(g) → 7CO₂(g) + 8H₂O(l) + Heat Energy
Health Hazard of Heptane
Because of the highly volatile nature of heptane, it can cause sight dizziness in humans, exposures to higher levels caused vertigo, in-coordination, and inappropriate behavior.
Uses of Heptane
⇒ Heptane is used as a thinner for rubber cement
⇒It is also used to extract cooking oils (such as soy oil) from seed.
⇒ It is widely used in the laboratory as a non polar solvent.
Important of heptane in gasoline
Octane Number/rating: A measure of the ability of a gasoline to prevent engine knocking. Gasolines with a higher octane rating are less likely to cause knocking.
n-Heptane (iso-octane) is one of the main components of gasoline (petrol). When used as a test fuel component in anti-knock test engines, a 100% heptane fuel is the zero point of the octane rating scale (the 100 point is 100% iso-octane).
Because of it's high octane rating it is widely used as gasoline(fuel)
