Of all the halogens, fluorine has the lowest atomic number and displays the highest reactivity. Chlorine comes next, followed by bromine and then iodine. Astatine is mostly ignored in chemistry; radioactive and rare, it does not often appear in nature. Halide Compounds & Alkyl Halides When hal...
Describe chemical tests that could distinguish between acetic acid and acetaldehyde. Describe how you would test an unknown sample for the presence of the chloride ion (Cl-). How are the chemical formulas of halogens and halides different?
which is more reactive than a single σ bond. For instance, olefins readily undergo electrophilic addition reactions with various reagents, such as halogens or hydrogen halides. The π electrons serve as nucleophiles, attacking electrophile
Usually, liquid oxygen gas has a light blue colour. This substance ishighly paramagnetic; therefore, we can make it suspended between the poles of powerful magnets. Its density is about 1141 g/L, which is slightly denser than liquid water. Moreover, this substance is cryogenic, having a very...
The key difference between valency and charge is that valency indicates the ability of a chemical element to combine with another chemical element, whereas
