no, false
I Believe The Answer Is Natural, But I Am Not Sure...
although it is a non polar covalent .It definetely has some % ionic character(very less)
C-H is a covalent bond because the electronegativity varies by less than 0.5 units
If electronegativity varies by more than 1.4 then you are most probably looking at an ionic bond. A variance less than 1.4 means, usually a covalent bond can be formed. This is a rule of thumb and is not always reliable. Metal to nonmetal; ionic. nonmetal to nonmetal; covalent.
PCl3 has covalent bonds. The difference in electronegativity between P and Cl is not large enough. The electronegativity of P is 2.19 and for Cl it is 3.16, and so the difference is less than one, making it a polar-covalent bond.

an ionic bond involves a transfer of electrons from the less electronegative atom(s) to the more elect. neg. atom(s) to form charged ions that interact with each other by columbic forces ionic, covalent, polar covalent
An ionic bond is expected between K and Br.
Generally, if the difference of electronegativity between the two elements are less than 1.7 according to Pauling's scale, they form a covalent bond or otherwise an ionic bond. Although there are exceptions such as hydrogen fluoride (which is covalent but the electronegativity difference is 1.9 approximately).
In comparison with ionic bonds, the difference in electronegativities of elements in a covalent bond have a lower difference in electronegativities. A covalent bond occurs between two nonmetals that have a difference in electronegativities that is 1.7 or less. Usually an ionic bond has a difference in electronegativities that is greater than 1.7, but not always.
The strongest electron shared bond is the covalent bond. The covalent bond is much more stronger than a single bond but it is also much less stable.
A bond between fluorine and sodium would be covalent (non-ionic), as they are both nonmetals, and the difference in their electronegativities is less than 1.7.
