Answer:
True
Explanation:
Aromatic compounds undergo substitution rather than addition reactions because the aromatic structure is maintained.
Electrophilic aromatic substitution begins with attack of the electrophile on the aromatic ring to yield a delocalized intermediate called the arenium intermediate. Loss of hydrogen from this intermediate yields the final product.
Answer:
A
Explanation:
Benedict's test is the ideal standard test to distinguished between reducing(glucose) and Non reducing(diasaccharides,sucrose).
Benedict's tests gives a positive test for the presence of reducing sugar,with the initial mixture of the sugar solution changing from the initials green and orange color and brick red precipate of copper (ii) ,which would not dissolve in solution.
However, with non reducing the Benedict's gives a negative test.Because no color change occurs.
In either case,the chemical reaction that occurs as the solution gained heat is exothermic and this may lead to boiling of the solution and spilling onto the burner,which may lead to explosion.
As bond number increases (double bonds rather than single, triple rather than double etc. ), bond length decreases and bond energy increases
Reason-Charges that are spaced apart are described by a dipole moment. There are two critical criteria that must be taken into account when assessing if a molecule has a dipole moment. It must first possess polar covalent bonds. The individual dipoles must not cancel out in the molecular structure, which is the second requirement. Because Br2 is not a polar molecule, it lacks a polar covalent bond.A bond number is a simple addition of two numbers that total the sum. Using number bonds, one can quickly determine the answer without performing any calculations. We can see from the example that when we see a number bond, we know the answer without having to calculate.

Answer:
The answer is Ionization energy.
Explanation:
Ionization Energy. The ionization energy tends to increase as one moves from left to right across a given period or up a group in the periodic table.
