inert gas
ketone
halogen
alkane
Answer is Right!
Answer is Wrong!
The correct answer is: C. halogen
Chlorine, fluorine, and iodine are all halogens. Halogens are a group of elements in the periodic table that are highly reactive and form salts with metals. They are also known as the “salt-forming elements”.
The other options are incorrect.
- Inert gases are elements that have very low chemical reactivity. They are also known as noble gases.
- Ketones are organic compounds that contain a carbonyl group (C=O).
- Alkanes are hydrocarbons that contain only carbon and hydrogen atoms, and are saturated (all bonds are single bonds).
