Question

Assertion :Sulphuric acid does not follow the Octet rule .
Reason: In Sulphur atom 3d – Orbitals are also available for bonding and hence it has 12 electrons around itself in Sulphuric acid. 
1) A and R are true and R explains A
2)A and R are true but R does not explain A
3)A is correct but R is incorrect
4)A is incorrect but R is correct​

Answer 1

Answer:

The correct option for this question is option 1) A and R both are true and R explains A correctly.

Explanation:

The assertion here states that Sulphuric acid is not following the Octet rule that is it is having more electrons than 8 which is called the extended orbit. It is so because it has some 3d orbitals which help it to accommodate more electrons and therefore it has 12 electrons around it in the acid and therefore the reason given here is also correct. Therefore the correct option for it is option A that is both assertion, as well as the reason, is correct and R explains A correctly.

Answer 2

1) A and R are true and R explains A

• Some elements in periods more noteworthy than period 3 on the periodic table have a d orbital accessible with a similar energy quantum number. Particles in these periods might keep the octet guideline, however, there are conditions where they can extend their valence shells.
• The octet rule can be 'extended' by certain components by using the d-orbitals found in the third head energy level. Sulphur is one of the examples of such an atom.
• This is the reason why Sulphuric acid does not follow the Octet rule.
• Hence, A and R are true and R explains A.
