Question

For H₂SO₄ (i.e. sulfuric acid). What is the theoretical number of octet electrons?
40
46
44
48
42

Answer 1

The valency of H is 1

S is 6

O is 6

There are 2 Hydrogens so number of valency electrons are 2*1=2

There is only one S atom so the number of valency electrons are 6*1=6

There are 4 O atoms so the number of valency electrons are 4*6=24

But hydrogen having 2 electrons after bonding is non an octet (having 8 electrons)

S&O are having 6 valency electrons so after bonding it acquires

Total number of octet electrons are 1 S & 4 O atoms

Therefore the number of octet electrons are 8(from S)+[(4*8)from 4 O atoms]=40
