First of all , what is 'c2h6o'??? If you mean C2H6O , then the formula is usually written as
CH3CH3OH
CH3CH2OH is ethanol ( acetyl alcohol) The alcohol that humans frink in beers, wines, and spiritis.
It is a COVALENT molecule.
It does not have ionic tendences.
However, the 'OH' functional group can be substituted for an halogen or amine.
NB When writing chemical formula . For single letter elemental symbols it is a CAPITAL letter 'C' for carbon, not 'c' . Similrly 'H' & 'O'. For two letter
symbols , first letter is a capital letter and the second leetter is small/lower case. e.g. 'Na' ( Sodium' Latin for Nadium).
NNB You misunderstand between 'Ionic' and 'Molecular'. All substances are 'molecules'. The bonding within substances can be either 'Ionic' or 'covalent'.
Neither
sodium on its own is neither it is simply an element. When in a compound it will always be ionic as sodium is a metal
Neither. Radiation is energy, and not made of matter.
Iodine has the molecuar formula of I2
Neither. It is hydrogeneous.
Neither
c2h6o means ethanol
Neither. Table salt is an ionic compound.

No it is ionic
C2H6O = 46.08 g 508 g * (1 mol C2H6O/46.08 g C2H6O) = 11.024 mol C2H6O There are about 11 moles in 508 grams of ethanol.
Neither. Radiation is energy, and not made of matter.
Nd (neodymium) is an element, so it is neither ionic nor covalent.
Neither Radon (Rn) is a element. Onlycompoundscan be ionic or covalent.
Neither. It is hydrogeneous.
Iodine has the molecuar formula of I2
Rubidium by itself is neither ionic nor covalent. When it forms bonds with other elements, it forms ionic bonds.
