An Intiative by Sri Chaitanya

$d_{C - C} (C_{2} H_{6}) > d_{C - C} (C_{2} F_{6})$

$d_{C - C} (C_{2} H_{6}) < d_{C - C} (C_{2} F_{6})$

$d_{C - C} (C_{2} F_{6}) = d_{C - C} (C_{2} H_{6})$

Detailed Solution

The structure of C₂H₆ is:

The structure of C₂F₆ is:

In C₂H₆, there is no electronegativity difference between C and H whereas in C₂F₆, there is electronegativity difference between C and F. As a result, partial positive charge is generates on both C atoms of C₂F₆. This results in shortening of C-C bond length of C₂F₆ so that the electrons between two carbon atoms becomes close and try to stabilize the positive charge on carbon atoms.
