|
|
A bond that forms when two ions have an attraction based on their charges, resulting in one ion stealing valence electrons from the other.
|
|
|
A bond that forms when one atom has a higher electronegativity than the other, resulting in an unequal sharing of valence electrons.
|
|
|
A bond that forms when partially positive and negative charges in different molecules interact with each other to form a substance.
|
|
|
A bond that forms between two atoms have similar electronegativity and equally share their valence electrons/
|
Detailed explanation-1: -Polarity of water molecules This is because the oxygen atom, in addition to forming bonds with the hydrogen atoms, also carries two pairs of unshared electrons. All of the electron pairs-shared and unshared-repel each other.
Detailed explanation-2: -In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond.
Detailed explanation-3: -Thus, the statement which correctly describes covalent bonding is (C), statement (3). Covalent bonding involves the sharing of electrons. The bonds that are formed are strong and require a lot of energy to break them.
Detailed explanation-4: -The area around the oxygen is somewhat negative compared to the opposite, hydrogen-containing end of the molecule, which is slightly positive. Opposites attract, so this lopsided charge difference allows bonds to form between the hydrogen and oxygen atoms of adjacent H2O molecules.
