It is a toxic substance that is no longer used in gasoline in most countries due to its environmental and health impacts.<\/p>\n<p>A. Pain Killer: Tetraethyl lead is not a pain killer. Pain killers are medications that are used to relieve pain. Some common pain killers include acetaminophen, ibuprofen, and naproxen.<\/p>\n<p>B. Fire Extinguisher: Tetraethyl lead is not a fire extinguisher. Fire extinguishers are devices that are used to extinguish fires. There are many different types of fire extinguishers, each designed to extinguish a specific type of fire.<\/p>\n<p>C. Mosquito Repellent: Tetraethyl lead is not a mosquito repellent. Mosquito repellents are substances that are applied to the skin or clothing to prevent mosquitoes from biting. Some common mosquito repellents include DEET, picaridin, and IR3535.<\/p>\n<p>D. Petrol Additive: Tetraethyl lead was used as a petrol additive to improve octane rating and reduce engine knocking. Octane rating is a measure of a fuel&#8217;s ability to resist knocking in an engine. Knocking is a type of uncontrolled combustion that can damage an engine. Tetraethyl lead was effective in reducing knocking, but it is a toxic substance that is no longer used in gasoline in most countries due to its environmental and health impacts.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;Pain Killer&#8221; option2=&#8221;Fire Extinguisher&#8221; option3=&#8221;Mosquito Repellent&#8221; option4=&#8221;Petrol Additive&#8221; correct=&#8221;option1&#8243;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[692],"tags":[],"class_list":["post-21612","post","type-post","status-publish","format-standard","hentry","category-general-science","no-featured-image-padding"],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.2 (Yoast SEO v23.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Tetraethyl lead is used as A.
