Explanation:Br2 , bromine, is a diatomic element, or a molecular element is NOT an example of a compound. Because it is made up of just one element, hydrogen gas (H2) is a molecule rather than a compound. Because it is made up of hydrogen (H) and oxygen (O) atoms, water (H2O) ...

A nucleophilic substitution reaction is a chemical reaction in which a nucleophile (an electron-rich species) attacks an electrophile (an electron-deficient species) and replaces a leaving group (often a halogen atom) in a molecule. This type of reaction is common in organic chemistry, ...
but is a straightforward consequence of the fact that the electron density accumulates in the vicinity of the covalent bond – especially for more polarisable halogens such as bromine and iodine. This redistribution of charge is accompanied by an ‘equatorial’ band of negative charge between these...
