Question

- (1) What is a homologous series of substance?
(ii) Explain, why carbon forms compounds mainly by covalent bond?
(iii) What type of bond is present in Cl2 molecule?​

Answer 1

Explanation:

Carbon has 4 electrons in its valence shell. ... Also, it cannot gain 4 electrons because the nucleus cannot hold on to the four extra electrons added. Therefore, to complete the octet, it shares 4 electrons with other atoms. That is why, carbon forms compounds mainly by covalent bonding.

Answer 2

Answer:

pls mark me brainleast... God bless you

Explanation:

1)In organic chemistry, a homologous series is a sequence of compounds with the same functional group and similar chemical properties in which the members of the series can be branched or unbranched, or differ by -CH2

2)Carbon has 4 electrons in its valence shell. ... Also, it cannot gain 4 electrons because the nucleus cannot hold on to the four extra electrons added. Therefore, to complete the octet, it shares 4 electrons with other atoms. That is why, carbon forms compounds mainly by covalent bonding

3)covalent bonds

In covalent bonds, like chlorine gas (Cl2), both atoms share and hold tightly onto each other's electrons. In our analogy, each puppy again starts out with an electron bone. However, instead of one puppy stealing the other's bone, both puppies hold onto both bones.
