Which of the following best explains why the bond in propane (c3h8) are non polar covalent

option C - Carbon and Hydrogen have similar electronegativity values.

Explanation:

Carbon form COVALENT compounds with hydrogen. Examples are methane CH4, ethane C2H6, propane C3H8.

Electronegativity is the power to attract electrons. It is used to predict whether a bond will be covalent OR not. It can also be used to predict if the resulting molecule will be polar or nonpolar

Thus, Carbon with an electronegativity value of 2.55; and Hydrogen with 2.20 shows close similarities and THUS result in NONPOLAR and COVALENT BOND of Propane

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
