( SF ₆ ) is a kinetically inert substance because
Options
- Afluorine is highly electronegative
- Bit is sterically protected
- Cgreater difference in electronegativities of ( S ) and ( F )
- Dlarger size of S-atom
Correct answer
B. it is sterically protected
Step-by-step solution
In ( SF ₆ ), sulphur is (s p^3 d^2 ) hybridised. Both geometry and shape of the molecule is octahedral. ( SF ₆ ) is also a non-polar molecule (dipole moment, ( =0 ) ), because if (a⁻ )and sterically protected perfectly symmetrical molecule. So, ( SF ₆ ) is also kinetically inert.
