It can bond with another atom to gain 3 more valence electrons (-3)
Answer: option a and d
Explanation:
Option A- Benzene undergoes substitution reaction
Example : benzene reacts with chlorine to form chlorobenzene, in the presence of Iron
(iii) chloride as a catalyst
C6H6 + Cl2 ---> C6H5Cl + HCl
Option D- Benzene also undergoes addition reaction
Example: benzene reacts with hydrogen , in the presence of nickel as a catalyst to form
cyclohexane
C6H6 + 3H2 ---> C6H12
Reasons why Option B isn't the answer
Although benzeme has degree of unsaturation but it's not five degree of unsaturation.
Benzene has 6 carbon atoms and 4 degrees of unsaturation (1 ring and 3 double
bonds).
If you work backwards and double the degrees of unsaturation you have 8 degrees of
unsaturation instead of 5.
Option C - Benzene isn't a saturated hydrocarbon
Is this from connections academy?
The process that is occurring as iodine solid is transformed into iodine vapour is SUBLIMATION.
Sublimation is the process by which a substance transformed from a solid state straight into a gaseous state without passing through the liquid state. Iodine is capable of undergoing sublimation process and this property is usually used to separate iodine from mixtures.<span />
The elements calcium, gold, iron and sodium are all metals. They all have a tendency to donate their valance electrons, rather than acquiring additional valance electrons. They all form metallic bonds, in the form of a shared electron cloud. They all have the electrical conductivity and metallic luster which comes with metallic bonds.
