What is a polar covalent bond
Answers
Explanation:
Polar Covalent Bonds. A polar covalent bond exists when atoms with different electronegativities share electrons in a covalent bond. ... The unequal sharing of the bonding pair results in a partial negative charge on the chlorine atom and a partial positive charge on the hydrogen atom.
Answer:
Have you ever seen two children play and one child acts like a bully toward the other child? The bully child seems to spend more time playing with the toy than the other child. They are not equally sharing the toys.
This unequal sharing also happens with a type of bond called polar covalent bonding. Polar covalent bonding is a type of chemical bond where a pair of electrons is unequally shared between two atoms. In a polar covalent bond, the electrons are not equally shared because one atom spends more time with the electrons than the other atom. In polar covalent bonds, one atom has a stronger pull than the other atom and attracts electrons. Remember how electrons carry a negative charge? Well, when electrons spend more time with one atom, it causes that atom to carry a partial negative charge. The atom that does not spend as much time with the electrons carries a partial positive charge. To remember a polar covalent bond, instead say 'puller covalent,' and remember one atom has more 'pull' on electrons than the other atom.
