The table shows the electronic structures of four elements.
Element Electronic Structure
P 2,6
Q 2,8,1
R 2,8,7
S 2,8,8
a. Identify which element(s) will form covalent bonds with carbon.
b. “Carbon reacts with an element in the above table to form several
compounds.” Give suitable reason.
fastest answer will be brainliest and answer should be well explained.
Answers
Answer:
a. R and P are the elements that forms the covalent bonds with carbon
P - Oxygen
Q - Sodium
R - Chlorine
S - Argon
Oxygen bonds with carbon to form CO2
Chlorine bonds with carbon to form CCL4
Sodium donates an electron, so it does not form a covalent bond
Argon is a nobal gas, so it can not form a covalent bond
b.Carbon has a valency of 4(also can be called as Tetravalency OR Caternation)
Carbon reacts with an element in the above table to form several
compounds
For example:
Carbon reacts with Oxygen to form CO2 and CO
Answer:
(a) Elements P and R will form covalent bonds with carbon.
(b) In the above elements, carbon reacts with element P to form several compounds.
Explanation:
(a) Covalent bonds are formed between atoms by sharing of electrons. From the given electronic data, we can determine the elements as -
P - Oxygen(O)
Q- Sodium(Na)
R- Chlorine(Cl)
S-Argon(Ar)
Na (Q) is an alkali earth metal and therefore it does not form any covalent bond. It only donates electron to form ionic compounds.
Ar(S) is an inert gas, therefore it cannot form compounds with carbon.
But, Oxygen(P) and Chlorine(R) having great electronegativity can form covalent bonds with carbon by sharing of electrons.
(b) Carbon reacts with oxygen(P) to form various compounds such as-
Carbon dioxide, CO₂
Carbon monoxide, CO etc.
The reasons for forming different compounds with oxygen are-
(1) Catenation property: The property of carbon to self link with other carbon atoms.
(2) Tetravalency: Carbon can combine with four atoms due to its tetravalency.
Therefore, the answer to (a) is P and R and the answer to (b) is P.
