<u>Solution:</u>


<u>Answer:</u>

When orthobromoanisole is treated with sodamide (NaNH₂) and ammonia (NH₃), benzyne is formed and the tripple bond is formed between C₂-C₃ carbon atoms of benzene ring. Then NH₂⁻ can attack at ortho position as well as meta position.
The reaction takes place in three steps. Step-1:The amide NH₂⁻ ion attacks the H
-atom that is ortho to C3
, generating a carbanion. Step-2:Loss of Br
- to form a benzyne intermediate.Step-3:Addition of NH₂⁻ ion. The strain caused by a triple bond in a benzene ring can be relieved by a nucleophilic addition of NH₂⁻.
Two isomeric products are formed: (1) <em>o</em>-methoxyaniline and (2) <em>m</em>-methoxyaniline. The structures of both the isomeric products are given in diagram.
Answer:
второй ответ является правильным
Explanation:
химическое соединение заключается в том, что
Base unit is the fundamental unit of measurement that is not mutually dependent. The seven base units are,
Length - meter
Mass- kilogram
Time - second
Temperature - Kelvin
Current - Ampere
Luminous intensity - Candela
Amount of matter - mole
Derived units are derived from the seven base units. Like the area (square meters) is the square of length (meters), volume is the cube of length.
