Question

In a polar covalent bond,

A. electrons are shared equally between atoms.

B. a cation is bonded to an anion.

C. electrons are transferred between atoms.

D. electrons are not shared equally between atoms.

Answer 1

A covalent bond is characterized by the sharing of electrons. A polar covalent bond is characterized by a unequal sharing of electrons.

This is something to commit to memory.

Answer 2

THANKS do you no this one? Water has a higher boiling point than expected because

A. there is so much water vapor in the atmosphere.

B. water molecules are not very massive.

C. hydrogen and oxygen form single covalent bonds.

D. of the strong attractions between polar water molecules

Answer 3

Boiling water does not separate the bond between the hydrogen and the oxygen, it simply breaks the bonds between the water molecules.

If we know that polar molecules have charged poles (water is highly polar)as illustrated, we can image the individual water molecules as magnets. If these magnets are stuck together, it would take more energy (in the form of heat) to break these intermolecular bonds.

Armed with this information, what do you think the answer should be?

Answer 4

well i say its d but im not sure?

Answer 5

D is correct. Water molecules have strong polar attractive forces, kinda like magnets do.

Answer 6

lol thanks that picture really help will u help me with some more?
