The electron pair in a C-F bond could be considered Question 3 options: closer to C because carbon has a larger radius and thus exerts greater control over the shared electron pair closer to C because carbon has a lower electronegativity than fluorine an inadequate model since the bond is ionic centrally located directly between the C and F closer to F because fluorine has a higher electronegativity than carbon

Ответ:
closer to F because fluorine has a higher electronegativity than carbon
Explanation:
Electronegativity refers to the ability of an atom in a bonding situation to draw the shared electrons of the bond closer to itself.
Electronegativity increases across the period and decreases down the group. A highly electronegative atom draws the shared electron pair of a bond towards itself.
When two atoms are bonded together, the electron pair is always drawn closer to the atom that has a higher electronegativity.
Hence, the electron pair in a C-F bond could be considered closer to F because fluorine has a higher electronegativity than carbon.
Ответ:
2.67 x 10⁷km
Explanation:
Given parameters:
Time of arrival of p-waves = 2: 10: 00
Time of arrival of s-waves = 2: 15: 20
Unknown:
Distance of wave from epicenter = ?
Solution:
To find the distance of the wave from the epicenter;
Distance = 3 x 10⁸ x time interval
Time interval = Time of arrival of p-waves - Time of arrival of s-waves
= 2: 10: 00 - 2: 15: 20
= 5min 20s
= 320s
Now, we need to convert the time to hrs;
3600s = 1hr
320s = = hr
So,
Distance = 3 x 10⁸ x = 2.67 x 10⁷km
