Electronegativity difference of C and H:
yes
no


Yes  

Explanation:

EN of C = 2.55

EN of H = 2.20

    ΔEN = 0.30

Yes, there is a small electronegativity difference.

It means that a C-H bond is slightly polar — about 97 % covalent and 3 % ionic character.

That is such a small difference that we often say a C-H bond is nonpolar.

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
