- BTo prevent freezing of petrol
- CTo increase boiling point of petrol
- ✓As an antiknock
✓
Answer
Correct option: D.
As an antiknock
d
One member of the octane family, isooctane, is used as a reference standard to benchmark the tendency of gasoline or $LPG$ fuels to resist self-ignition. For example, gasoline with the same knocking characteristics as a mixture of $90 \,\%$ iso-octane and $10 \,\%$ heptane would have an octane rating of $90$
