Question

Which one of the following statements is false

1. a nonpolar covalent bond occures when two atoms with completely different electronegatibities share electrons
2. in an ionic bond, the atoms do not share electrons
3. a double bond is shorter and stronger than a single bond
4. when an atom with a high eklectron affinity takes an electron from an atom with a low electron affinity an ionic bond is formed
5. a bond made between carbon and hydrogen will be nonpolar

Answer 1

A nonpolar covalent bond occurs when two atoms with similar or low differences in electronegativity share electrons equally. This means that statement 1 is false.

Step-by-step explanation:

A nonpolar covalent bond occurs when two atoms with similar or low differences in electronegativity share electrons equally. This means that statement 1 is false. In contrast, a polar covalent bond occurs when there is a difference in electronegativity between the atoms, causing the electrons to spend more time closer to one atom than the other.

1. In an ionic bond, the atoms do not share electrons. Instead, one atom completely transfers electrons to the other, resulting in the formation of ions.
2. A double bond is shorter and stronger than a single bond because it involves the sharing of two pairs of electrons between two atoms instead of just one.
3. In an ionic bond, an atom with a high electron affinity does take an electron from an atom with a low electron affinity, resulting in the formation of an ionic compound.
4. A bond made between carbon and hydrogen will be nonpolar because carbon and hydrogen have similar electronegativities and share electrons equally.
