Why was Niels Bohr’s atomic model superior to all the earlier models?
Elena L [17]

Answer the correct option will be option B.

Explanation: this is how he showed the electron could orbit the nucleus without falling into it. This is so because he explained that the electron  revolves around the nucleus  in a fixed circular orbit with fixed energy and cannot occupy just any energy level which is defined as quantisation of energy.

option A is one of postulates given by Dalton in his Dalton's atomic theory which later proved to be wrong.

option C  it is one of the postulates given by the in J.J Thomson in his model of  an atom which was the first atomic model.

option D Schrodinger has used the wave nature to explain the position of electrons around the nucleus.

Examine the general structure of a molecule.
Lilit [14]

Answer:

Explanation:

functional groups are specific substituents or atoms within molecules that brings about chemical reactions of those molecules. There is the same or similar chemical reaction in compounds with the same functional groups.

1.)The functional group in Alkyl halides is halogen atom whille

The functional group in Alcohols have

is OH group. There is a double bond in HX or an HOH molecules.

2.)The functional group of carboxylic acid is an organic compound is carboxyl functional group.While The functional group in amine contains a basic nitrogen atom with a lone pair of electrons.

3.)The functional group in ester is a carboxylic acid derivative that is analogous to the Amides

4.) A carboxylic acid has carboxyl functional group. However the hydrogen of the hydroxyl group is can be ionized. In an ester, there is a replacement of hydrogen of acarboxylic acid group by an alkyl group
