It is each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.
Answer:
This reaction is an example of Hydrohalogenation reaction of alkene.
In this reaction the double bond of alkene acts as nucleophile.
This reaction follows Markovnikov's rule i.e. the bromide will add to more substituted carbon atom.
This is because the carbocation intermediate formed during the reaction is is more stable due to its secondary structure.
The final product is called 2-Bromopropane.
1. D (explanation is shown in the picture above)
2. A,B&E are diatomic molecules in standard conditions.
Answer:
see below
Explanation:
the charge of the atom is neutral because there are equal numbers of protons and electrons in an atom.
