no option is 2,2,4tri methyl pentane but when u try to compare its structure with the others in the option, you'll see that A is the best option here.some questions are like this,they require the most suitable and not 100% accurate answers
NO CORRECT OPTION
The anti knock agent is 2,2,4 trimethyl octane
But the only one close to it in the option is the 2,2,4 trimethyl butane
Myschool pls u need to edit the options
C8H18
Ocatane from Alkane (CnH2n+2)
No crrt option but easily you can get it through reading the carbon bonds and hydrogen bonds also m. option A is very much close
there is no correct option here
the compound that can be found present in the refined or petrol that helps it burn smoothly is 2,2,4-trimethylepentane. this compound reduces knocking in the engine vehicles as it prevents wearing out of the machine parts. in addition, the tendency of the amount of this compound in the Petro will determine how well an engine rense will last as it is inversely proportional to the knocking that means as u increases the anti knock the knocking reduces and vise versa. while the compound that can be added to the petrol that has lower composition of 2,2,4-trimethylepentane to avoid knocking is pentane. and that cause the removal of black carbon through the exhaust pipe.
