An electric force is exerted between any two charged objects. Objects with the same charge, both positive and both negative, will repel each other, and objects with opposite charges, one positive and one negative, will attract each other.
Explanation:
Ionic bond for eg:-NaCl which is very strong
Answer:
4200ml
Explanation:
Converting 3.1kg to g
3.1*1000= 3100g
Since density = mass/volume, then
volume = mass/ density
Therefore volume = 3100/0.74
= 4189.2ml
converting it to two significant figures
= 4200ml
Answer:
NHCOR
Explanation:
In electrophilic aromatic substitution, certain substituents on the aromatic ring such as
-NHCOR are known to enhance ortho-para substitution. These ortho-para activating groups stabilizes the intermediate cation.
These ortho-para activating groups usually consists of species that donate electron density towards the reaction centre thereby stabilizing the carbocation and making the reaction faster.
