Bonding Flashcards
1
Q
Bond polarity occurs when
A
One atom is more electronegative than the other, eg H—Cl is polar ,but Cl—Cl is not
2
Q
Define electronegativity
A
The power of an atom to attract the pair of electrons in a covalent bond
3
Q
What makes an element highly electronegative
A
Low amount of shielding
Low atomic radius
High nuclear charge
4
Q
What is the most electronegative element
A
Fluorine
5
Q
A molecule is non-polar when
A
It is symmetrical (can still have polarity, but it is evenly distributed)
6
Q
A molecule is polar when
A
It is unsymmetrical, the dipoles are not evenly distributed (this also includes lone pairs)
7
Q
A polar molecule can form what imfs
A
Permanent dipole-dipole and H bonding
8
Q
A non-polar molecule can form what imf
A
Induced dipole-dipole
